Walmart.com is offering the silver astromech outfitted 7915 Imperial V-wing Starfighter at a 25% discount, down to $15 even. Shipping to home is .97 cents; alternatively, you should be able to pick it up at your local store for free. Tax applies where applicable. Normally, Amazon will quietly match the price but it seems that Amazon doesn’t have any in stock; just fulfilling orders for third party resellers.
Thanks to SugarConroy for the tip.
