Hey there! I think you could shave a lot of money off that list. For starters don't go to a mainstream pet store first they really will charge you $10 for a mister but walmart it will be only a few dollars. I understand it being your first pac you may want to have a more aesthetic setup but pacman frogs can do just fine with a minimalistic setup. Many breeders do not even keep their pacs in terrariums but in rubbermade containers which is perfectly acceptable. As for a shelter its not really needed as long as you have a deep bedding of ecoearth. I like having a broad leafed fake plant that will provide good amount of top cover so that the pacs can hide under the leaves. I personaly feel that the pacs will feel a lot safer if they have a fake plant for top cover this will only cost you about $10. An undertank heater is strictly dependent on your house temp. As for lighting you wont need anything fancy I recommend getting a electrical timer from home depot that will run you only about $5 for a cheap one I set mine for a 12/12 photo period. You will need to get a calcium powder WITH d3 that will run about $7. For cleaning you can just spot clean as you see poop appear most of the time it will be in the water bowl, ontop of the bedding or in a old burrow. Cleaning your bedding out depends on the frog and how well you spot clean depending on how much bedding you put in you could keep it in for 2 months or so poop may not build up but ammonia will. As for feeding insects should be the staple with a pinky/fuzy according to frog size every few months or more frequent to add on weight if necessary. If you have anymore questions let me know I know this is a pretty big wall of text so I will leave it here for now hehe!
