You wouldn't say a thing...
If I was in a store, and someone in front of me was shelling out a large amount of cash for something, I'd try to start up a conversation about why they're doing it. I'd suggest alternatives, but the choice is always theirs.
So you do this in every store where there are cheaper alternatives available? Supermarkets, clothes stores, electronics stores, licquor store......... 'hey there, why are you buying those Nike air's for $150 don't you know you can get some trainers from walmart for $10 or you could get some second hand ones on eBay' - likely to get a punch in the face. I really do think you are just being a dick for the sake of it now. Nobody here has a problem with your opinion that you don't want to spend alot on old carts, and you wish you could get them all cheap - the problem we all have is your expectation to get stuff from members at below market value, and your vociferous , undermining the opinions of those who choose to pay the market value, on multiple threads. It's just being a dick, and you are really annoying a number of people who have the ability to ban. And just so you are aware, we ban at IP level, so you can't just set up a new account and start again.
That's not a threat of a ban, just a heads up if you thought you could wipe the slate clean and start again. Maybe just go have some quiet time, and then think a little before you start spamming another thread.
I would imagine this thread will be cleaned up in the next day or 2, and put back on track.
