I would think Sears, or International Clothiers would be your best bets. Possibly even Walmart or Target?

Otherwise, Google and the interwebz FTW

I don't mean to sound preachy, but if you learn how to tie a tie, when you're at any formal event preparing around other guys, you instantly because a hero if you know how to tie a tie. Not to mention thank you beers.

On the other hand, if you're really not comfortable. Buy a regular tie, get the clerk at the store to tie it, when you take it in and off loosen the tie and remove it over your head rather than undo the tie completely. You can hang it on a hanger and it's good to go indefinitely.
