I had an experience where it said FREE SHIPPING on the eBay ad, but when I went in to purchase it, it added $15.00 for shipping. I couldn't figure it out for a minute, then I read the FINE PRINT, and you had to buy more than a specific number of the items to get FREE SHIPPING!! It was very deceptive.
In all these transactions, remember BUYER BEWARE!!! It's YOUR responsibility to check out EVERYTHING before you agree to buy.
