An easier way to rob shopkeepers than the famous wip+jump method that i find more difficult and inconsistent at least for me.
All you need to do is move the items to the right near the exit point, clear the way so you can have room to just grab the shotgun, use the rope method to stun him and run. Rope stun is really easy as you can see in the video just stand in the same spot throw a rope and immediately grab the shotgun and run.
I did not discover this method just saw so many videos using the rope method that ended up killing the poor shopkeeper.
Your goal is to grab the shotgun and RUN LIKE HELL, nothing else matters, don't try to get items especially explosive ones. If you kill a shopkeeper then you'll need to deal with angry shopkeepers for the rest of your run, if you use this method and just rob him you'll be forgiven after just 1 level. Make sure you'll not kill the shopkeeper in the next level and you'll be golden.
Having a shotgun and potential extra items as early as 1-2 will make your runs so much easier.
Good Luck!
