We just had a Brownie field trip to Build a Bear on Saturday. The limit was $20 per girl, so we told them they could all pick a $10 or $12 bear. Then the outfits were supposed to be an $8 or $10 outfit, depending on the bear they chose. Instead of that, one of the leaders and I went and picked 1 of each of the $8 outfits and brought them to the girls to pick from. This way they didn't overwhelmed by all the selections and want the more expensive ones. It worked very well, and they had a pretty good selection of $8 outfits. My dd got a bridal outfit with a really pretty headpiece. It's a very nice outfit, and it was $8. There was also a bunch of pajamas (so darling, lot's of girls picked those) a denim dress, a flowered dress, gymastics outfit, basketball uniform, white blouse with plaid skirt. It was a lot of fun, and if you set limits and ask them to set the price limited outfits aside for you, it can be kept reasonable.
