Is there such a thing as an Online Dollar Store?

Technically there is only one exclusively Online Dollar Store which is Dollar Fanatic at www.dollarfanatic.com an exclusively Online Dollar Store that sells everything for $1.00 each, with free shipping when you order $50 or more.

The items for sale come from a wide range of categories and some are extreme values that have retail prices up to $14.99 for only $1.00 each. They also offer volume discounts on certain products. Dollar Fanatic does have lots of limits and restrictions on products so you can’t just buy everything in the quantity you want which can be a little irritating at times

Of course, there are a couple major players in the Dollar Store Industry that focus primarily Offline, however they do have Online options and don't sell everything for $1.00 each.
