Samsung's top-of-the-line Galaxy Tab S series is hard to beat, unless you're a stickler for "clean" software. If the TouchWiz skin and the physical navigation buttons don't bother you, then both the 8.4" tablet and the 10.5" tablet offer top-of-the-line specs and unbeatable AMOLED screens. The larger of the two is on sale on eBay's daily deals portal today. You can pick up the 16GB Wi-Fi base model for just $279.99, an impressive $220 off of the retail price, and $170 cheaper than Amazon.
A couple of caveats: one, while the tablets are marked as "new," the seller seems to think that the definition requires a few conditions. "This item shows virtually no signs of use," says the seller notes, "it includes the original package (which may be lightly distressed) and the original OEM accessories." So, yeah, this might in fact be a refurbished unit, especially since the seller claims to be offering their own 1-year warranty. Even so, the low price might justify the risk, and it comes with a free Samsung-branded "pouch" carrying case.
Like most of eBay's featured deals, this one comes with free shipping, but unfortunately it's only available in the United States (and even then you're out of luck if you live in Alaska or Hawaii). Oh well: Samsung is due to refresh its tablets in a few months at the latest, at which point these deals will become more common.
