Payments:  We accept all forms of traditional and online payment methods available – Cash, MC, AMEX, VISA, DISC, PayPal, Venmo, Cash App, among others.  Payment can be made online or over the phone.

**Products we sell: At BPRATV we sell parts from the best names in the industry.  Unless otherwise stated, we will put the quality of the parts we sell up against any other companies’ in the industry.  Also, we stock the same parts from different manufacturers so that when back orders occur like they have been for the last year we have an alternate part to send that is the same quality.  This would be the ONLY reason your order might be slightly different when it arrives.  We NEVER sub a cheaper part EVER without contacting you and offering you a partial refund.  If you want a certain brand part just ask (if part is back ordered this may cause a delay on your order).

 Returns: Please check your order completely when you receive it and contact us if there is an issue.  99% of problems can be easily solved without returning the entire order.  We accept returns within the first 30 days.  If you are returning an order because buyer “Changed Mind” it is subject to a 10% restocking fee plus a deduction for our cost shipping the order to you.  Orders must be sent back 100% complete and all parts must be brand new, never installed, in the original packaging to receive a refund for them.  Once items have been modified, installed, or used in any way they are not eligible for return.  It is the buyer’s responsibility to ensure returned parts arrive to us in the same condition they were when they left our facility.  For more info about returns see the eBay Return Policy. 

 *Warranty: We stand behind all parts we sell 100%.  Everything we sell has been tested hundreds if not thousands of times and when installed and tuned correctly they work over 99% of the time.  Part failures happen, but it is rare that it is not due to being installed incorrectly.  If after installation there is an issue contact us for a warranty return.  This product is NOT DIY.  Over 99% of people in the world are not qualified to build an engine, and it is the responsibility of the person assembling and tuning the engine to make sure everything works correctly.  It requires special tools and has to be done 100% correct.  Many parts must be measured down to .01”.  We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic.  Warranty does not cover failure that is a result of improper installation, tuning, break in, or misuse.   STUD WARRANTY: If for any reason a stud fails during use, not installation, we will send a completely new stud kit.  No other parts or any labor are included, and it can not be converted to a refund or discount on any order.  Studs must be returned to us for inspection first.  ALPHA CUB WARRANTY: If your Alpha Cub cylinder fails for any reason not related to installation, tuning, break in, or misuse we will fix the cylinder free of charge.  If it can not be fixed we will supply you with a new one.

WE DO NOT WARRANTY PARTS BASED SOLELY ON PHONE CALLS, EMAILS, PHOTOS, VIDEOS, WHAT YOU READ ONLINE, OR WHAT ANOTHER MECHANIC SAYS IS THE PROBLEM.  WE HAVE A VERY GOOD WARRANTY PROGRAM BUT FOR ANY WARRANTY TO BE CONSIDERED THE PART(S) IN QUESTION MUST BE SENT BACK TO US TO INSPECT.  NO EXCEPTIONS.

Feedback: Positive feedback is greatly appreciated.  We have changed the way we do business in response to customer concerns and receiving positive feedback when an order goes the way it is supposed to is a huge help.  If you do not feel we deserve positive feedback just contact us and we will do what is needed to help you feel as "positive" as possible about your experience.  Also, we want information from customers when their experience is less than desirable so we know what areas need improvement the most.  Please work with us and we will ALWAYS work with you.
