I had a couple of issues with orders not transferring across (partially paid orders), but when I reached out through the Help channels they got sorted quickly.
However, there's still a few issues with the new site:
All pricing switches from Euro into Sterling once I log into my account (I'm Ireland based) - which is inconvenient, but not the end of the world. However, I'm noticing big discrepancies with the Euro prices currently on the website that are not accounted for by VAT and currency fluctuations. For instance, my order for the 'IE 22000 Class 'ICR' - 6-car in post-2013 IR livery - DCC Sound Fitted' is in my order as £919.95 inc VAT (and £747.93 ex VAT). However, the Euro version of the website says I can pre-order the set for €799.96 inc VAT (or €650.37 ex VAT). Maybe that's the currency symbol issue DJ mentioned above?
This forum isn't an official support channel, and I'll follow up directly with Accurascale (its a while before the 22000s will land anyhow) but its a bug that can cause a bit of confusion for customers.
Edit: just double checked my invoice (the pdf document) to see its €919.95 (and €747.93) ... its just my online order that reads as £919.95 inc VAT- so it looks like the currency symbol bug DJ mentioned alright.
