Did 2 trades with them. Few things I learned:
-- You definitely won't get street price on your trade-in.. so consider you're paying for the convenience and time saved of not having to sell it yourself. You will however get a fair and accurate trade-in price for your item.
-- You will pay ALL shipping. Pay to ship in your trade and then shipping on the new item to you.
-- If you trade in a scope of greater value, you're issued a credit. You do not get cash back or a gift card. You have to call the store in person during business hours to use the credit. The credit doesn't show up on your account when you log in. The credit is good for the whole SWFA store not just the sample list items.
--It might take a few days for them to respond to your trade-in appraisal.
It's pretty easy to do. I would do it again if I found a good deal on a Sample List item. You know what you're getting for a trade in value before entering into the deal. They are very firm on their prices, both trade in values they offer you and the used items they're selling.
