Basic e-commerce for such things as mop-buying is a solved problem in 2011. Not sure why you would even need a large team of top-notch developers at a place like Target. A few good sysadmins and DBAs, and maybe some graphics/front-end types.
Edit: Upon thinking about this a moment longer, I think that actually there would be (or could be) interesting work at Target, simply because of the scale of the operation. Though sadly you are still probably hitting the mark in the "bureaucratic drag" assessment.
Target is the third largest brick and mortar retailer in the US. Running a computer network nationally for Target is not a solved problem. Sure, it's a solved problem for #1 WalMart, using entirely custom software that WalMart developed in house. But it's not like WalMart is selling that software to Target.
