StoreApps: I checked again and the variations are definitely ordered from high -> low. Changing the order that the products are listed in to be low -> high doesn’t change the variation order. I’d really appreciate if this option can be added.
Telemarker: Thanks for taking the time to help with this. Unfortunately I’m not sure what to do with the code that you’ve given me above. I’m not used to modifying the code manually, I’ve just used plugins for pretty much every customisation of my site up until now.
