"Hey we don't have this part in stock, but we can order more as long as you meet the minimum of 25 parts"
"Okay, well, I only need 20, so that's annoying, but otoh they're only $0.3/ea, so sure why not"
*a few hours later*
"Hey so uh, our website was wrong, the minimum order isn't 25 parts, it's a whole 1,000 count reel... So uh yeah we're guessing you'd like to cancel that order?"
Annoying. In fairness the reel pricing would get the unit cost down to $0.25/ea... But also I don't need 980 spare PLCC sockets, do I.
