Bests & Worsts Reviews from Amazon

I should have known better. I always, always, always read Amazon user reviews and I can't think of a time I didn't heed their warnings -- until now. Many reviewers stated that mybatterysupplier shipped dead (or nearly dead) batteries, but I figured those users must have received the rare bad batch. I mean, seriously, how hard is it to ship fresh batteries? I needed a CR2032, and at 5 batteries for $4.99 (with free Prime shipping), I figured it was worth a shot. WRONG! The batteries arrived promptly and the packaging looked just as it did in the ad. The "Use By" date on the package said 2021, so I figured I was all set. WRONG! Right out of the package, three of the five batteries registered "Replace" on my battery meter (the $3 battery tester from Amazon -- [...]details -- which is amazing, btw). I didn't bother testing the last two batteries. I printed out a return label and searched for this product by this seller so I could leave a negative review. I clicked on the order link directly from the My Account page . . . and what d'ya know . . . The link now lists the seller of the $4.99 Sony 5-pack batteries as Best Deal Supply, not mybatterysupplier, and all the very bad reviews for mybatterysupplier have mysteriously vanished. Maybe these are the same companies, maybe they aren't. I have no idea, but the timing of the name change is awfully convenient, as is the disappearance of all the negative reviews for mybatterysupplier. Do yourself a favor. Don't bother with these batteries. Unless you need a whole lot of CR2032s, spring for the extra few bucks and buy one at your local drug store. NEXT-DAY (12/20/2011) UPDATE: I went to see if my review was published and almost laughed out loud. When I bought these batteries at the end of last week, the seller was listed as mybatterysupplier. Yesterday (when I wrote the review), the seller was listed as Best Deal Supply. Today, the seller is listed as Photoland NY! What's the story here? Does this company change its name every few days to erase prior negative reviews?
