It probably won’t last long, but you can get the SDCC-exclusive Jabba the Hutt figure for retail price (about $65) now on HasbroToyShop.com. Unless the bottom totally falls out of the market, this is likely the cheapest it will ever be.
[Edit: These have now sold out. Only took about an hour. However, HTS has been known to restock, so it wouldn’t hurt to check back later if you missed out. Also, eBay prices have really nosedived since SDCC, so it probably won’t be hugely more expensive to get it that way if you have to.]
