When I worked overseas we had to order from netgrocer.com, which is an online grocer. When you think of groceries, are you only thinking of produce and meats? We'd order canned and non-perishables mostly.
Some of the guys I worked with sold a lot of extended warranties by scaring people into thinking their purchase could break or fail in a million different ways. I never liked that tactic, hence I wasn't much good at selling the warranties. But really it's the company's fault, they really stress the warranty sales because it's basically pure profit for them. Still understandable that it would be upsetting to hear some of the sales bs.
