Hi,
I'm just new to this but I use Box It In which is an Ebay shop.
I don't know how they compare price wise as my dad in law has been in business for eighteen months and has shopped around ... he recommended them to me.
They were very helpful. I'm a bit of an Ebay phobe and it was my first crack at Buy It Nows, the lady on their help line was very helpful and the whole thing went without a hitch.
Delivery next day too.
Good luck
