I have seen kits for sale that are $49.00 and higher, but you can make your own kit for much less using supplies you may already have at home. My mom made mine by buying a cute vintage looking box from Ross for less than $10 and filled it with the following:
Aspirin, Sewing Kit, Safety Pins, Nail File, Kleenex, Mints/Gum, Compact Mirror, Clear Nail Polish, Band-Aids, Band-Aid Blister Blocker, Bobby Pins, Visine, Hair Spray, Deoderant, Tide Stain Remover Pen and Double Stick Tape.
We ended up using only a few of the items, but we had a VERY small wedding party (just a Maid of Honor and Best Man) so no real emergencies, thank goodness! But I was glad we had everything “just in case”!
If you still want to purchase one, I found this one at www.scarfonlineshop.com?for $49.00.
