I went to Forever 21 this weekend and spotted their v-neck camis and basic scoop neck camis for only $2.80 each. That's the lowest price I've ever seen for camis! I bought one in each color.
I also found them online, but if you don't want to pay for shipping, get the camis in the store.
Update: The price is now just $1.59 for this Hello Kitty earrings, necklace, and ring set!
