Found out from a neighbor that these are on sale for 40% off.. i think today only. Plus free shipping!! Warning, the site was a little slow for me this morning and stuff was becoming out of stock.

DS is going into K next year, and they had a train one so I snagged it! Excited to give it to him for his Christmas present. Anyway, I was advised from several mamas to get the Large size (even for a K'er) since Small is too small for school folders and extras like water bottles, change of clothes etc.
