With orders of $25 or more, Amazon offers the Alex Toys Rub a Dub USA Map in the Tub for $3.13 with free shipping for Prime members. (Walmart charges the same with in-store pickup.) That's $6 under last week's mention and the lowest price we've seen. (It's the best deal now by $16.) It includes 74 foam puzzle pieces that float and stick to tile when wet.

Note: This item is part of Amazon's add-on program and can only be purchased with orders of $25 or more.
