Beware. You get a cost for shipping on their website, they charge your card, they arrange collection, then "audit" the shipment and charge your card again.
When I disputed the second charge they kept sending a default reply that they would provide details for the second charge, but never did, and then charged my card with the same amount AGAIN!
An initial quotation of £96 was charged £96 + £126 + £126, for a total of £348.
I am now disputing these payments with my bank, but beware of ParcelCompare, it's definitely a fly-by-night operation, never trust them
