This might just be a new record for number of errors in a single sentence:
It’s unimaginable to me (and to most English speakers) how the writer could think that sentence is okie-dokie for publication. She didn’t notice that prices starts is a grammatical horror? Or that prices can start at $700 and also go up to $1500. But there’s only one starting price for any item. And prices … is sold? That one made me spit out my sugar-free, nonfat vanilla latte. That’s so bad, I almost didn’t notice the random and totally unnecessary at.
