You are aware of what you are doing, so it should have been resolved, but now the goods have been purchased, so you don't need to regret it, just enjoy the shopping and use it as best you can even if you don't really need it 
On the other hand, talking about manipulation, actually I still feel this comes back to myself, but this is quite natural because indeed when we have money, whether it's important or not, as long as we want it, even if it's for a moment, we will definitely buy it and it will happen to you.
I think that something like this doesn't only happen to you, but most people have experienced this.
Indeed, sometimes it is difficult for us to control when we have money, especially if we shop with friends, relatives or someone special. Yes, we can't think long and hard when we see the items we want to buy at that time, and with no burden, of course, we will voluntarily buy these items. Yes, this kind of thing must have become an open secret, although in the end the same thing is repeated, yes, we finally realize that what we buy is not really what we need. But when everything has happened, as you said, then use the item properly, or I usually sell the item again, even if it has to be sold at a lower price.On the other hand, talking about manipulation, actually I still feel this comes back to myself, but this is quite natural because indeed when we have money, whether it's important or not, as long as we want it, even if it's for a moment, we will definitely buy it and it will happen to you.

You can also confess it directly to them and I think they will understand you. A hammer is more superior than a nail so it's better to be a hammer. Money is only just a thing so it should not control us. There are still ways to live properly with a less money on hand and some people have proved it already. These people are in fact more happier now.
