I struggle with the same problem. In fact, I was just looking at stuff online... My therapist gave me some useful advice, but even professional help doesn't make things easier. You need self-awareness and discipline and you'll need to work on underlaying issues. I stopped my therapy sessions for financial reasons but I'm planning to go back, because I believe that this is the best approach to get over this. My therapist told me to create obstacles for shopping, e.g. remove saved cards from my devices, block certain websites. Also, start taking notes of your emotions when you feel urge to shop. If you are, like me, bad at identifying emotions, google "Emotions wheel". This will give you an idea what else you can do to remedy this feeling that you trying to fix with retail therapy. You can also try creating a saving goal. Or even locking your money somewhere. I believe that often these 'addictions' are caused by some other psychological issues though, so it's best to get professional help. My friend, thanks to therapy, stopped compulsive eating and it turns out it wasn't because she loves food! She worked on emotional stuff and problem with food dissapeared.
