two words: WAL-MART
they have a pack of 36 condoms for like $12. Like sexy malibu said. And they have ribbed ones, spermicide ones, lubricated ones, non-lubricated, spermicidal lubricated, flavored and colored ones, trojan twisted pleasure, warming sensation, you name it, they probably got it. Its awesome. If me and my boyfriend used condoms, i'd get them there.
I'd reccomend spermicidal lubricant. Just grab a box of 36, and go to the register. And pay. Get your bag, and walk out the door. They dont card you for condoms, dont worry. Haha. And they do usually last for a couple of years, but dont carry them in warm places like a wallet. A good idea would be to get an ID case (a metal one) and store them in there in your pocket.
Or, if you want to make things interesting, if you're at a wal-mart supercenter, buy like 2 packs of 36, whipped cream, hot fudge, cherries, and a BIG bottle of KY warming sensating lubricant. And just smile. And go to a female cashier. Dont even say a word. Just smile. If she asks you a question, say youre gonna have a very happy gf tonight.
