Was surprised to find out that the bit of my preview order which I wanted exchanging does not qualify for a credit, even though the item I want ( in exchange) are not in stock.
Basically, my maths showed the difference between what I returned and what I have re-ordered is minus £69 -ish, as the tank top is out of stock for 2 months. BUT as it is an exchange they are hanging on to my money until the tank top is in stock.
Make sense? well yes, but it's quids in to Johnnie this way and not me.
