I've googled & found answers all around this issue except this particular case:
Long story simplified:
I pre-ordered 2 items from a US mail order firm. Shipping was say £25 for 1 item, & came out as the same for the 2 = I was billed £25 shipping.
Today they email & say they 'should' have charged that amount per each, & can I confirm I'm happy to pay double ie £50 I haven't actually paid anything yet just submitted the order, so they would re-invoice me.
Me: checks website & find they have indeed changed the postage now.. but to a different, greater amount say £35 for 1 - also the cost for 2 (& in fact for any quantity, I tested up to 5).
Presumably I have them over a barrel over trying to charge double but are firms entitled to up their postage costs on a pre-order ie can I even argue I shouldn't have to pay £35?
Thanks.
(fuming actually, asking for extra shipping is one thing - if it was a mistake they should just swallow it imo - but when their facts are not even correct. incompetence! and it's at least my fourth dim-witted business interaction inside a fortnight.
