Diapers in retail stores tend to be pretty bad. I like Depends Protection with Tabs more than a lot of ABDLs but it's not high capacity. Some medical supply stores or non-chain pharmacies have better selections but it will take time to work that out. The best I know of that appear in stores are Tranquility All Through the Night (ATN), Molicare Super Plus, or Abenas. I don't really care much about pull up diapers but Abenas were the best I tried. Abenas in a store are sort of the four leaf clover, so not sure if the pull ups are a more or less common presence in those few that would stock them.
Really, if you want something good, buying online is your best bet. If receiving is a problem, you can try having them deliver to a UPS store.
