AMPEFI will make every effort to ship all in stock orders placed by 2pm EST, on the same business day. If your order is not in stock you will be notified during the checkout process prior to completing your order. We strive to keep all items in stock and will communicate clearly with you about the status of any orders placed for items that are out of stock.  Thankfully, this isn’t a frequent issue as we keep a close eye on our inventory, so normally we keep all items in stock ready to ship the same day!

International Shipping

We will gladly ship anywhere in the world via USPS Mail or upon request via UPS/Fedex.  If UPS/Fedex are requested we will contact you regarding any additional cost involved as UPS/FedEx is generally more costly than USPS.  Generally it’s 2-2.5x the cost of USPS Express, but it gets there really fast ;).


International Shipping – Reducing declared value to reduce customs fees

Unfortunately, we cannot mis-represent the value of shipments in order to reduce customs duties. We really do understand your pain; some countries charge as much as 60% import/customs tax. We’re sorry, but we really can’t mis-label the packages as we would be putting ourselves and our business at risk when doing so;  Greater than that, we want to be completely straightforward about everything, with everyone. We promise that in all of our dealings, we’ll be just as honest and straightforward with you. Thank you for understanding.


Shipping Insurance

Shipping Insurance is available during checkout for $1.30 per $100. We will provide this insurance either directly through the courier or through an independent insurer so we request you contact us directly with any issues. We do recommend shipping insurance for high value packages, as well as for international packages. We cannot be responsible for uninsured packages that may be lost in transit. We’ve not experienced  many problems with this so far and hope we never do.


Signature Requirement

Priority mail shipments do not normally require a signature. If we recognize your shipping address as an apartment we will often mark your package to require a signature since the package is at high risk sitting outside your door. This costs us extra to do but it’s worth it to us to make sure you receive your order safely. All Express Mail shipments require signature unless you specifically request that your shipment should not.  We cannot be responsible for packages that are lost/taken after delivery even if insurance is purchased– the insurance covers the package until it is delivered, once delivered it’s out of USPS hands and therefore they can’t guarantee anything.  Hence the benefit of requiring a signature– someone has to be at your home or place of business to claim and sign for the package…


Cheaper International Shipping Methods

Due to popular request we’ve added a couple of less expensive shipping methods for international orders.  There is more risk involved with cheaper methods, and therefore we must ask that you accept and agree to the policy below in order to select them.  The shopping cart will prompt you to accept this policy in order to checkout using one of these methods:


We’ve been in business a long time now, and shipped tens of thousands of packages, and we’ve lost VERY few.  I could count on one hand how many.  We’ve always stuck with the trackable, insurable shipping options in order to deliver this level of service.

We do have some international customers however that would like to see cheaper shipping options, especially for light or low value packages.  Because of this popular demand, we’ve added some cheaper shipping options.  Here is an overview of the new options:

New International  options:

  • First Class International (3lbs or lighter only, max $200 value)
  • Priority Mail International (weight limit varies by country, max $250 value)

All available shipping options will display during checkout based on package weight, value, and destination.

It’s important that you as the customer understand that there is higher risk in shipping with these cheaper methods.  They do NOT support Tracking, or Shipping Insurance.  For a long time we were hesitant to offer these methods because of this, because we want to be able to guarantee your package arrives safely.

That said, due to popular demand for cheaper shipping options, we’re going to try this out.  These methods can save you several dollars in some cases, but you must understand:

  • We cannot guarantee a time frame for your order’s arrival.  The USPS’s estimation does not take into account customs delays, or some guy at a dock somewhere putting the package in his car to ‘inspect’ it further at home.
  • We cannot track the package.
  • We cannot contact the Postal Service, here or abroad, concerning a package shipped with this method.  They can’t track it either.
  • We cannot insure a package shipped with one of these methods.
  • We cannot replace a lost order shipped with one of these methods.

In our experience, the cheaper domestic options are still pretty reliable, just slower.  However depending on the country we’ve had some problems with international packages disappearing with no way to track them when shipping with the cheaper international methods.

We’re offering these options to you so you can make the choice on whether you’d like to pay a little more for speed and security, or go with a cheaper option, throwing caution to the wind to save a few bucks, which in some cases makes sense to do.  It’s your call.

If you understand and agree with this policy, please check the box below and click the continue button.  If not, click cancel and choose a slightly pricier option that assures you that your package will be trackable, and optionally you can pay for insurance in the event it would be lost along the way.


Sales Tax

Orders placed in the state of Georgia are subject to a 7% sales tax. We do not collect taxes on orders to other states or international orders; there is currently no national US sales tax. Most international orders are subject to tariffs or taxes upon arrival. This is collected by the government in the country the order was shipped to and AMPEFI has no control over these taxes. We recommend checking with your local customs office for the most up to date information.


Items may be returned within 45 days of their original purchase date.  RMA can be opened in that 45 day window with our support department ([email protected]) and we must have the items back in our hands by 50 days after the order was shipped originally.  This gives us the time to process the refund within a total window of 60 days which is the max allowed by some of our payment processors.  With the following exceptions, un-opened and un-tampered with items with all packaging in it’s original condition may be returned for a 7% restocking fee.

Please contact us prior to returning your order so we know what to expect and include a copy of your sales receipt with the return ensuring that your email address and phone number are included as well. Once the return is processed we will refund the remainder of the original total, minus the shipping/handling and restocking fees.

Returns must included any original packaging, should be visually perfect just as they arrived (no scratches, etc), wiring should be original length uncut, and everything should function perfectly.  If this is found not to be the case additional fees will apply or we may have to refuse acceptance of part/all of your return request.
