Walmart offers the LEGO Architecture Arc De Triomphe for $31.99. Opt for in-storepickup to dodge the $5.99 shipping fee. (Amazon charges the same.) That's $3 under our mention from August and the lowest price we could find now by $6. This set includes 386 pieces.

Update: The price has increased at Walmart; however, Amazon still offers it for $31.99 with free shipping for Prime members.
