Here is a terrific clearance item from Walmart.ca that would be perfect to put away for next year! You can currently purchase a Fisher-Price Thomas & Friends Minis toy engines advent calendar for just $8. These are regularly $29.97 and will go fast at just $8. I only ever got the calendars with the chocolates in them as a child, and these would blow those out of the water. With 24 mini toys that is just 33 cents per toy, or per day, however you choose to look at it!
The box folds out into a railroad track to drive the toy engines on, making this a must for any wee Thomas fan you may have.
You may be lucky enough to find these in store as well, but they may not be $8. I did see the Despicable Me advent calendar at my Walmart after Christmas, but it was still priced at over $16.
