Yes but anyway would be more "normal".....at least....
Maybe they wanted to start "higher" withn 80$ to accomodate any negotations, but 800!!!! It's just CRAZY! As I said I'd ask if it is a typo! Hopeful it is a typo!
I usually ask that when I see a crazy price on ads, is the only question you can do sometimes at certain pricing! This is the most "delicate" and implicit way to say "hey what the hell?" without looking like if you want to get cost down and negotiate.....this would maybe let them think a bit and so look around to see what's the "average" price going.... and maybe realize the real value...
Sometimes I found people that said thanks and it was a mistake, other times no they were convinced....what you can do in these istances is to let them realize it theirself with no response coming.....
