I know the Amazon price fluctuates a little over time, last night when I checked the AT-TE price it had moved up to $65.99, but it is back down this morning. Target also has some nice pricing (online only), they are offering free shipping on select items and they are also starting a free store pickup on sets that you generally find offered in their stores.
Currently Target matches the Amazon price on the AT-TE, Republic Gunship, Jek-14's Stealth Starfighter & Jabba's Sail Barge but you can also take advantage of a coupon for $5 off a Lego set priced at $29 or above. The coupon code is TGCDNTUZ.
This coupon might expire tomorrow as it has been in place all week. The pricing on Target's website hasn't been this good all week though and I notice some prices fell a little between last night and this morning. Some good deals outside of the four noted above, and before the coupon savings, are:
9516 - Jabba's Palace $81.99
9493 - X-Wing Starfighter $43.79
75005 - Rancor Pit $40.99
75017 - Duel on Geonosis $30.99
I also like the Castle line and I ordered 70403 Dragon Mountain for free store pickup for $27.99 pre-tax, post coupon which is 44% off MSRP.
