Although I guess I shouldn't be posting this information since I am not a Mom and the OP is requesting info from a Mom.
Although I do have a Brownie troop of 6 girls, hoping to get more girls and have been involved in Girl Scouts for 17 years non-stop since Brownies. I will be nice and share anyways
Scrapbook Supplies
I know of a few places to buy Girl Scout related stickers and things and also to find clip art. Girl Scout supplies are harder to find since Girl Scouts is very strict on licensing of their trademarks.
I'm making this into two posts the first one is places to buy supplies and this one is for clip-art.
Scrapbook-it has incredibly fast shipping and awesome customer service. I think I ordered my stuff from there on Monday night and it was here by Wednesday afternoon. I had ordered a paper doll set from them and it was missing the dolls. They told me they would send me replcaement dolls. I ended up with a complete set of paper dolls and all of the clothing pieces and I didn't need to return the package with just the clothing pieces.
Scrapbook Lover's Dream has a good variety of Girl Scout products as well. These items were ordered on the same day as from Scrapbook-it but took almost a week 1/2 longer to arrive. Although they sent me a handwritten apology letter since it took so long to arrive. So I suspect this was abnormal.
They have these Accordion album kits for the various age levels. The Brownie level is $4.23 it includes
# 1 Sheet Bazzill Basics Cardstock Stonewash
# 1 Sheet Bazzill Basics Cardstock Walnut
# 1 Sheet Cindy Kids Brownie Cardstock
# 1 Sheet Autumn Leaves Ribbons and Patches Paper
# 4 Deluxe Cuts Mini Chocolate Chip Cookies (1 package)
# 1 Yard Blue Twill
# Instructions on how to make an Accordian Album from 12 x 12 cardstock
At first glance the prices for both of these sites look the same although scrapbook lover's dream shows a list pirce and then when you click on the item for a description they have a lower price.
Create For Less Has some supplies, I have not purchased anything from them.
Another place to check is ebay and do a search for supplies. I found some really neat Girl Scout rubber stamps of the handsign, the trefoil, gold award, etc. from seller: amazing_arts I use them on cards, memos letters to parents etc.
You might also try to contact your council some have supplies for sale. Although my council has none for sale so I had to look elsewhere.
Michael's, Joann's and A.C. Moore often time have camping supplies and other things that you might be able to use.
If you have a local scrapbook store they might have a die cut machine or even a Wishblade or something similar that you can use to cut out titles and shape die cuts. Some stores allow you to use them for free if you purchase the paper from them.
Another place that might have a die cut machine known as an Ellison die cut machine, is your local school that the girls go to. They might allow you to use it for free if you supply the paper. Some colleges and universities might have one as well for use by students and possibly others if they have an education department. Or maybe a local library might have one if they lots of kids programming.
