This effectively happened.

I ventured into a booth which was scrawled with great, siren-like signage declaring 20% OFF — with a fine print informing that the discount only applied to their main store, and only on selected items.

The booth staff did tell us that the merch was at an already discounted price, though.

So I walked around the convention, checked out the items I was considering purchasing at a few other booths, and the first vendor was the cheapest.

When I returned to booth, I found them crossing out the prices on their stickers and jacking all the prices up by $5-$10 dollars.

I didn’t buy the game.
