The 6" x 6" Glimmer Paper Assortment Pack (item 143831), which was an item you could earn for free during Sale-A-Bration, has sold out. You will no longer be able to choose this item as a free Sale-A-Bration item.
There are lots of other great items that can be earned for free during Sale-A-Bration though. Be sure to place your qualifying order by March 31 in order to claim your free item(s). Just remember, all Sale-A-Bration items are only available while supplies last, so don't wait too long or something else you want might disappear as well.
Don't forget that the Card Tin (item 143833) is also sold out already.
