If they know they can get away with their suppliers having to front all the cash, why not do it? If all their competitiors get away with it, they'd be fools not to as that is a lot of expense and interest they're eating and they'll need to make up for that somewhere.
Yes. And still not everyone wants to work for them. I'd sure never ever ever try to sell them anything... I'm thinking with such reputations they get shafted out of good opportunities and this has a cost. I'm not sure how Costco treats their partners & providers but I'd guess they're still shrewd without bullying and sell better quality. I know the business model is different but clearly there's room and money to win in other ways.
