That is very nice list . I replaced our old list of streamers in Support Resources with your link because it is much better formatted and I see you are still updating this . <| sep |> Every item you place gives you a certain amount of XP . Most of the time , I think , it ' s 10 % of the item ' s cost . This XP award is affected by your conformity bonus plus the hidden SH bonus , and can be boosted with the XP Collider . With enough cash on hand , and a high enough bonus , you can churn through quite a few levels , earning yourself a load of free donuts . Bloodmobiles are one of the most expensive items in the game and , being decorations , are placed instantly no build time . This is the quickest way to convert a large pile of money into donuts . KwikEMarts , however , award 2 , 000 XP per building with an increasing cost from $ 220 $ 14 , 400 , and are therefor much more efficient in terms of $ XP . The 4 hour build time , and the amount of land needed to house them , though , makes KEM farming less convenient . BM farming is good to dump a large stockpile of cash in one go . KEM farming is good to steadily spend your income as it comes in .
