I try very hard to quickly answer questions about products before the sale. If you are uncertain about a product please ask, I want to make sure that what you buy is what you need and what will actually work for you. If you buy a product and change your mind about it later and want to return it, I will have to charge a re-stocking fee and I can only accept returns on unused items. I can only make refunds for 60 days after the purchase through paypal. I do not refund the shipping or pay return shipping unless the reason for the return is on my end. Please contact me for instructions before returning anything. If I'm not expecting something to come back, I won't know what to do with it if it actually makes it to me. Some packages are shipped direct from the manufacturer and simply mailing something back to them won't get you a refund. If there is a problem with a product, please contact me so we can work something out. Some items are covered by warranty.
