My first stroller I paid big bucks for (by the time baby #3 came he deserved a few new things! ) but by the time baby #5 was on her way I scoured garage sales and found one grandma bought and used it only a couple times! A great find! And the baby didn't care!
I've seen those baskets that fold up at thrift stores, you know the ones "old ladies" use at the store or market...a friend of mine loves hers!
hauling stuff?? DOUBLE Strollers! I have two of the kind with reclining seats! Can't seem to part with 'em knowing I can take 'em to school, load 'em up and "haul" what I need inside. Also have the little ones "trained" to hang on to the sides and hold doors! I'm gonna miss those two when they start school....I got a few years!
Oh - one more tip. (The wagon idea is great - we used that in the neighborhood.) But if you are needing to transport a bunch of cookies from the car to a sales station, pack a nice big assortment in a suitcase with wheels. Much nicer than hauling boxes if you have to go very far.
Note - this isn't meant for if you have to open close it alot, like going door to door. But just from the car to a particular point.
Another good place is if you have any kind of local sporting event where they don't sell on-site concessions.
For example, in my area we have a lot of locally organized soccer and basketball groups. They play in parks or use elementary school gymns so there's no on-site concessions or policies that forbid food sales by others.
You can sell a TON of Girl Scout cookies in these situations.
I'm sure it differs by area, but around here we don't really take pre-orders, selling stock on hand. Also setting up a booth outside a retail store is tightly controlled and assigned at the Council level. (I guess store owners got bombarded by girls asking and it was also unfair for those who had friends/connections versus those who didn't.)
Another idea - about the same time as cookie sales, the Boy Scouts here have their Pinewood Derby. The local troops use our elementary school. A couple of hundred people trapped there ALL day and no food concessions. There's always an enterprising Girl Scout or two who cleans up on cookie sales.
