Autom has a great deal right now on a reusable Nativity Advent Calendar.  It is just $2.99, down from $9.99.  It says that suggested retail is $20, which I definitely believe.  I have seen this type of calendar even more expensive.  I don’t know what the quality is like, but you only use for a month each year!

Ground shipping is $5.95 for orders up to $15, so you might want to checkout their other Christmas sale items while you’re at it.  Sale prices are good until September 26.
