Ive just sold some stuff on ebay (well I'm hoping I have!)
Its basically 8 boxes, approx 35cm x 20cm x20cm and probably weigh about 1 kg each - so going to box in one parcel.
I was going to use parcel force, but I just had a quick online look at their prices - and think I can now see why they are struggling! Ye gods they are expensive! Cheapest was about £15 for 3 day delivery!
Anyway, Ive just had a quick google and found this one http://www.p4d.co.uk
which seems to work out at £6.99+vat and for that they even collect as well!
So - what do you use to send parcels? My only concern with being collected is just the fact they can turn up at anytime (and that includes when the missus might be on the school run - which is a concern!)
