Ha. I did a full Joja run before, and nobody in town really cared.
This time I completed everything except the last fish bundle, and I realised I'd have to wait almost a year because I had one fish missing. So I bought a Joja membership instead. The only reward I was missing were a bobber and I think possibly a supply of bait. Nothing worth waiting a year for.
I think I actually prefer this way of playing. I like having Joja mart, it's saved me a couple of times when I was busy on the farm and forgot to buy seeds before Pierre closes shop.
This way I get the fun of doing bundles, and finding the stone junimo - but I don't have to wait for that last elusive item in the last bundle. And I don't have to do the missing bundle, which is a pain to complete.
