I'm looking for some advice/suggesions:

We have two kids and one single stroller. My plan was to purchased a used umbrella stroller with a canopy for our upcoming trip. (They each have to have one). I was also going to send a box with cereal, snacks, detergent, etc. to the resort. I'm not exactly what else I'll put in it because I'm worried about weight and have no idea how much postage will cost.

When I visited the groceries and strollers site, they have a special. If I rent a stroller, which looks pretty nice, I can have groceries delivered without the delivery fee. Now I'm not sure what to do. I tend to focus a little too much on saving money....

Has anyone done either scenarios, or both? Tell me your experiences.
