not trying to bad talk them... I'm just saying I've never heard of that store/website and it just looks fishy
I personally would not feel comfortable buying either one, but at that price point, I guess it doesn't matter as long as they provide a warranty
Microcenter seems like a very legit store, especially if you actually have one in your neighborhood. I've only used them for internet purchases, but they are a step ahead of many other companies I've worked with in communication. I get an email when something gets backordered, I get a notice when that item ships, I can call customer support and get answers to my questions in a timely efficient manner, they've adjusted invoices for items that were backordered and the price was lowered while I waited for it to ship. They are an authorized Apple reseller, and while Apple isn't the best company in the world, they don't let any Tom, Dick or Harry sell their goods.
I use them in my MacBook Pro for HD video, have used them in an Olympus audio recorder, and used one of the 32GB that I have from Microcenter in my Pandora exclusively and have had no issues. Sometimes the MacBook Pro recognizes the card but won't let me write to it, but for recording on the fly in HD or audio, they take the abuse and give great results. I've never tested these because I've never had a need to, they work, friends have used them and not complained.
What I'm saying is that somewhere in Asia their are a few factories that are producing these cards, and they have a lot of different stickers. My two cents. Pay dumby lewt for a name you like if MicroCenter or A-Data don't meet your standards, but all memory fails eventually.
Lastly, they have real sales where you have to go to the store to buy a well marked down item, and you can only buy one. To me this still has real meaning in business sense, storefronts have value, and I still find myself at a place like Radio Shack when I'm in a bind for cables etc.
