buy cheap, buy twice

If something is inexpensive, it is probably poorly made or will wear out quickly (and one will have to purchase it again). A: "I need to save some money, so I think I'm just going to buy this cheap cell phone." B: "I'd be wary if I were you. You'll probably end up spending more money—buy cheap, buy twice, and all that." Dude, just invest in a name-brand instrument from the beginning. "Buy cheap, buy twice" is not ideal. Yeah, yeah, I know—buy cheap, buy twice. But these are the only work boots I can afford right now.
