I'm a "browser," too! I have a few favorite "junque shoppes," all of which have been closed for the duration. I managed to get a "fix," last week, when I happened to be out front when the proprietor of one was delivering more goodies. He wasn't officially "open," but he let us stay (we slipped in right behind him and his box. He didn't realize we were there and we didn't realize we weren't supposed to be. I just saw the open door and my reflexes kicked in!
We (DD, DS & I offered to leave, but since we were the only ones in the store, he let us stay and shop (he was allowed to be open, just wasn't, yet.) I had an entire antique store to myself!!!!! It was WONDERFUL! I found a little wooden chair and some antique textiles for making doll clothes. I'm happy ... and good for another couple of weeks before I need to root around again!
