The main thing is that people are dissuaded from buying 2nd hand car seats on account of them possibly maybe having been involved in a minor accident and there being an unknown issue.
Obviously that doesn’t stop everyone (we’ve had two out of three 2nd hand) but you’re sort of exemplifying that fact that we all tend to be hyperspecific about our kids here by the fact you want a particular seat type.
Anyway, broadly I think your plan is great but in execution you might have issues shifting the two car seats even if they’re in packaging as it only takes one parent to be full erring on the side of caution to scoop into your profits. Say you only end up making maybe £150 on each seat, is the hassle of selling them on going to be worth the extra £100 total?
