Hi L.!
I've used Peapod for many years. When they first started out they were affiliated with Jewel, then they branched out on their own and have their own warehouse of food.
In all honesty I would say that Peapod is more expensive. The prices tend to be higher, and when they have a "sale" generally the sale prices are what you would have paid normally elsewhere. Then of course on top of that you pay for delivery. I continue to use the service on and off because it's just more convenient when you don't have the time. But when I do use it, I keep in mind that I'm not going to get as many groceries as I would have shopping normally. Which is why I don't use the service for every shopping trip. Another convenience is that you can get more than groceries using Peapod. So that does help also.
Just so that you have the information you need to compare. I shop for a family of 4. I normally shop at Jewel or Meijer every other week, and I started using Peapod a few years before my youngest was born ... so I'd say I've been using it about 8 or 9 years or so.
Hope that helps!

P.S. L., I came back to add some things that I think you may want to know . . .
1. In all the time I've been shopping with them, something on each order has not been right. Meaning they either forgot items, or they brought the incorrect item. (They will issue a credit for this or attempt to redeliver).
2. If you use coupons, the coupons are credited to your account and the credit is given on your NEXT shopping trip. So if you don't use them again, you're not saving any money.
