I used to try to fill the box once before 11pm when Re-tail closes to empty it, and then sometimes I'd go back later to sell in the morning. I can normally fill the box with bugs worth 6000+ in less than 40 mins if I'm devoted to it.
If I only make one trip I make 250k-300k. My goal is to do it at least 2-3 times a day. I gotta save for home renovations. I was just curious if anyone else got bored with it.
