I especially enjoy going to Aldi's specifically for those unusual items. Plus growing up, we always went to Vogt's Import House for certain products that reminded my Mom of her homeland, so it's fun to see those things there, hokey, but like reminiscing.
I go on a whim usually or when I peruse their email flyer and see something I like. I don't do my regular gocery shopping there because you can't count on EVERYthing you might like being there week after week, which is disappointing sometime. I know people mention it's like a warehouse, but I've never felt that way. I rarely buy a cart either - I just take a reusable tote and buy what fits and that's it! lol
