Hello MMowned i no this isnt the best guide but it is usefull.
Now i dont no about you but my bank runs the auction house on Gorefiend, I sell everything. Primal might, Earth, Large prisimatic shards, Epics, Etc. Anyways i often found myself out of bag space and didnt want to use 100g for 12 slots, or buy a guild vault.
I found out that u can have free pag space for as long as u want for a cheap price. Put the item you wanna store on the auction house and cancel it. it can stay in mail for 30 days. just trying to help:wave:
