> Dollar Tree [...] You have to hunt for the bargains that are actually worth it

Ain't that the truth.

Sure, you can get a roll of aluminum foil for $1 at Dollar Tree, while a roll is $4 at Kroger. But the Dollar Tree roll is only 25 feet long, while the Kroger roll is 200 feet. And that $1 screwdriver in the tools section is made of chinesium and will either break or have the tip get warped if you have to use it on anything tough.

That all said, Dollar Tree is THE place to go for party favors. Gift bags for $1 when they'd cost me $5-12 anywhere else? That's a steal! I mean, sure they won't have licensed Disney/Nickelodeon/etc. cartoon characters on them, but I don't think even the kids notice.
