Do you take checks? -- Always confirm your payment arrangement in advance, since policies vary widely for checks and credit cards. At Tastebuds, for instance, credit-card orders must be faxed in, on company letterhead.
Volume discounts -- Most restaurants and delivery services have minimum-order requirements that can be met only if two or three workers (or one absurdly hungry one) pool their selections. Group ordering also helps defray delivery charges, which range from $2 at Teahouse Noodles to $5.95 at DeliveryMeFood -- including a $2 surcharge for an order that didn't meet the required minimum.
Something for the effort -- All delivery people rely on tips. DeliverMeFood.com's Quentin Piotrowksi suggests tipping just as you would a server, from 15 to 20 percent of the bill.
Stockpile sporks -- While most places provide the basics, extra paper plates and napkins will come in handy. And if your workplace allows it, a sharp knife is a big help for slicing sandwiches and pizza.
