[Request] Looking for a current set for a build-in-bag

I want to try a build-in-bag... I've tried buying a couple small sets at Target but have struck out both times. I can't find a source for bag information anywhere, so I'm hoping someone can just recommend a set that comes in one bag, not a polybag, and is readily available at Target or Walmart. I could possibly also make a trip to a LEGO store if necessary. Thanks for your help!
