This summer, I'll be traveling to USA in late July. I'm planning to get a 15" MacBook Pro (most probably by that time, the new ones will be out). The thing is that apart from USA I'm traveling to a couple of countries and cities, and I'm carrying cash only, because my bank's MasterCard doesn't always get accepted internationally, so I can't risk it. My question is, if I walk in at an Apple store, will they let me pay for the MacBook with cash? I've already done some research, and I can't seem to get a straight answer. Some say they don't accept cash just for iPhones and iPads. Others say they don't accept cash at all for anything. A few sites said they accept cash for everything. And I even read somewhere that they don't accept cash if it's over $500. Please help!
