I have used them many times...but only if they have promo codes/coupons. The fruit is always the best (always fresh, ripe and never bruised) and the meat is always the best cuts too! The delivery people always ask where they can put the groceries when they come in...very friendly and courteous. I would do all my shopping with them if the sales were good...but I find that once you add shipping cost to the delivery I save more with my double and triple coupons at the actual store...
But when I cant get out or am just plain lazy, I always use Peapod!!!
