Someone was kind enough to post that they had taken a Menard's ad to Walmart and were able to get Cricut Lite cartridges for $22.50! I don't have a Menard's here but thought I would pass on the information. Here is the link to the ad, MENARDS AD, but you will probably have to have the original ad in order to get the price match! The ad runs from 9/5 to 9/12.
Good luck, and happy shopping my Cricut friends!!
