I've already traded both of the other items that were in my bag. So now I really like all three items. We'll see what's in my bag when trading ends in seven days! If you're happy with the contents of your bag, you can choose to go ahead and ship it. Trying to trade up is very addicting though.
The cost for Little Black Bag is $49.95 per month with free shipping or you can try it once for $49.95+shipping. Like other subscription services, you can skip a month without being charged. So there isn't too much harm in looking...unless you get sucked in my shiny things as easily as I do.
