I know what you mean. I live in London. On Thursday, I fueled up at the chain you speak of in London for $2.54 about 4 p.m. Gas was so cheap at this chain in Lex, at $2.34, that I topped off. I get back to London around midnight, to find that same store had raised its price to $2.64 while I'd been gone. :(
