"if u summon a dremora for 60 secondas you can then kill it and steal its weapons (be careful using magic sometimes they have reflect) you must enter their inventory before they hit the ground otherwise they will disapearr. you can get items such as daedric dai-katana and longsword. you have a limitless supply of money." - Morgawr Mage

"Telekenisis is the best way to steal!
Make a spell of telekenisis for 100ft, then go into a shop and find a place where you can sneak and aim you crosshair at the item, then do the spell and voila! This work best when pickpocketing!" - Luca

"Glass armour at level 1 without cheating!
If you start as a thief go under the sign of the shadow straight after go to caldera and get the ring of aversion this will allow u to go invisible for 10 seconds, now head to ghostgate go to the person selling glass and use the ring of aversion to get everything off the shelf and leave a happy man (you can skip getting the ring of aversion but using moonlight shadow stealing an item sleeping 24 hours and getting the next item is a very longwinded experience)

Quik 80k

to get 80k simply goto the dren plantation and search around, there should be daedric and ebony armour but even more amazing is that there is a locked chest in the plantation with 80000 septims of cold hard septims" - Snake

"If you have stolen an ordinators amour and are wereing it dont talk to an ordinator otherwise they while attack you. if you kill them you wont get a bounty but but they will respawn and always come after you." - cobra 5
