I ordered these same slipper socks but in black from this same vender.  The advertisement clearly said "set of six" as does this ad for these blue ones.  I thought that was a weird way to sell socks but I did expect six of them (three pairs).  Only one pair came.  When I complained the merchant said that there had been a mistake in the listing and that they hadn't seen the "set of six" in the ad.  She said there was to be only one pair and to send them back and she'd refund my money.  I'd already warn them and refused to send them back.  She finally refunded my money and I kept the socks.  They're great and I like them a lot. Wish I had three pairs like I was promised!  False advertising, I'd say.  I notice the black ones aren't listed now except with another vender (could it be the same vender with just a different name...if it is they forgot to remove "set of six!" and haven't removed it from the blue ones either)  Those are listed for $5.00 more. If you really want these, and I definitely recommend them, order the more expensive ones from the other vender and then do what I did and complain because you didn't get three pairs as was promised.  They'll probably just give the ones you got just to get rid of you!

By the way, the socks were way overpriced at $11.95 per pair and are far overpriced at $16.95 with the other (same?) vender.  $5.99 per pair would be about right!
