I'm getting in on this...you Southerners...
If you're going to offer an item in exchange for cash, then you are going to "sell it"...you are not going to "sale it".
I swear I've never heard that until I moved here. I started hearing people say: "Yeah, I'm just going to sale it".
The other one that cracks me up is "just chunk it in the trash", rather than "just chuck it in the trash".
