I have made numerous purchases from Amazon.com over a few years time. I have never had a problem with them. Interestingly, I had given negative feedback about a food supplement that didn't do anything for me, as advertised. I wasn't asking for a refund but was issued a refund anyway? My intention was only to give an honest objective review?
Amazon also has many good deals. I purchased a TIG welder off ebay a few weeks ago for what I thought was a good deal. Later I discovered that amazon.com also sells welders! I didn't know that? I could have purchased my welder brand new for $82 less than what i paid, and the shipping was free! Now I check with amazon.com first before any other internet purchase.
