To keep or to sell???

[KristyMum]

I don't think you would be 'wasting' your money if you're receiving money by selling them... that would be 'making' money rather than wasting it iykwim

If you know you're definately not going to use then unless there is some sentimental attachment, sell them to fund the purchase/s of nappies you do like.
the other thing is that things like PUL and elastic won't last forever (tho they do have a good life), so how long would they be 'sitting', and the other thing is if you want to think about it this way, at the same time as you're receiving money for goods no longer used, you're giving someone else the opportunity to buy good s/hand nappies, when perhaps they would otherwise not be able to afford brand new...

Anyway, my 2c aside, I see you've decided to sell - have fun nappy shopping!

I agree with the others, sell and get some money back.... then you can make room for more purchases

Good luck
