Been using My Products for years too but just the auto listing feature, didnt bother with the rest, but yes I find it is good to use the sold page now and has everything we need, infact it might be better than the origianl sold page, .  Things seem hidden but they are there, like the envelope is to email the customer, down arrow to record the tracking number, blue top bar says its paid by ping,  search feature is good, etc.. still getting use to it, but yes I reckon go for it

I've instead gone to My products / sold and using that today It does have everything I need, once you figure out where everything is hiding  

BidBud is finally about to stop operating it says Its blocked by trademe for bidding
