I don't know about you, but I've never walked out of Costco EVER without spending at least $100. Even if I went in there JUST to buy a tray of cocktail shrimp for $9.99 (doesn't everything at Costco cost $9.99??), I always end up throwing a bunch of really good bargains (i.e. super delicious mega sized portions of whatever that lady was handing out at the end of the aisle) into my cart.
So today when I went in for a pack of AA batteries, I came up with a foolproof way to keep from overspending which I will generously share with you: Don't get a cart. That way you can only buy what you can carry.
As it turns out, I can carry quite a bit. 1 pack of AA batteries, 1 giant case of taquitos (hey, we're almost out!), a bag of truffles (teacher gifts are coming up, you know), some wrapping paper (I am addicted. Seriously, disturbingly, ADDICTED to buying Christmas wrapping paper. I'm pretty sure I could wrap all the presents in North America right now. But this paper was so cute...I couldn't resist!), a Christmas music CD two pack (um...no excuse for this one. Just a pure impulse buy) and a giant package of Oreos (you should see my kids inhale Oreos!). I am pretty sure my biceps increased by 2 inches by the time I got to check-out. BUT...only $57! Cha-ching!
So, almost foolproof. You're welcome.
