Things that I really like right now (and maybe you'll want to buy too):
Lemon Squeezer: Yeah, it's kinda expensive, but it was totally worth it for me. I used to use a lemon reamer and a small strainer placed over a measuring cup. Now, one tool quickly extracts juice (sans seeds) and I get nary a drop of lemon juice on my hands (which can be a literal pain if you have icky dry, cracked hands like mine).
Envirosaxs: I think we may have 4 or 5 of the Trader Joe's $.99 re-usable bags, and I keep them in my car in an attempt to remember to bring them in with me, but I forget all the time anyways. The fact that the Envirosax roll up and I can keep 2 or 3 in my bag and not even notice they're there is awesome and means I don't forget to bring them in the store with me. And the bagger at Nob Hill didn't even flinch when I busted them out before she could ask "paper or plastic". I bought the retro series from outdoorbalance.com and they shipped super fast.
Sally Hansen's Manicure Clean-Up Stick: My old method of nail polish clean up was a q-tip dipped in polish remover. I can't even tell you how much BETTER this clean-up stick works. It makes me so happy! Especially since I'm really loving the whole black nail polish on the toes thing, and messing up with black is pretty darn obvious.
I could have sworn there was one more thing, but I can't remember what it was. Three is a good number though, don't you think?

I like that the description on the lemon squeezer says:
fits 1/2 a fruit.
Thank you so much for talking about reusable grocery bags! I work at a food co-op in Austin and people are always forgetting their bags, sighing, then asking for plastic because "I promise I'll reuse those!" Having a sturdy bag to carry heavy groceries in is one of the tiny pleasures that can make your day so much better.
Did you happen to see the leather ones in May's Vogue that cost (seriously) a thousand dollars? It must be amazing to be fabulously wealthy.
ahh the manicure stick! i used to have one but then it got all crudded up cuz i always use dark colors for painting my nails :(
i agree with the lemon squeezer! I wish i could splurge on the envirosaxs. I bought a LOT of cloth ones with the solid bottom from Whole Foods and LOVE them. I keep like 5 in my car, a couple of them in my hubbies car and a few at home. It's soo much easier to carry all my groceries from the car when they've got the nice handles! If i go to the store without them...then i buy more! They are only a dollar at Whole Foods. I've found that when i'm bringing them in with me from the parking lot- there's always a women who comments "Oh, that's such a good idea- I ALWAYS forget to bring mine"
