buying off trade me

for those that buy off tm, do you prefer to buy single nappys, or together in a set...i'm downsizing the stash but not sure what works best...

Depends on the brand. I think if china cheapies or fuzzis/honeychild you are better off selling as a set, but the more unusual 'designer' or 'collector' brands you are better off selling individually. If selling as a set seperate out the girlie/boy ones, as otherwise you will lose half your market for the more unisex ones.
And always sell one size together, not all mixed up.

I prefer in a set! Tends to work out a bit cheaper overall.
