Price & Comment - Price doesn’t remain?

[JackyJacquard]

So I decided to start tracking the prices of my purchases after finding I don’t know them for a bunch of stuff I now wanna sell (Amazon’s opaque invoicing especially unhelpful here). Found my oldest order, about 40 items, entered the retailer (HMV) and the price (£7.19) in the ‘Price’ field not the comment.

Go back to them now, its disappeared. But if I enter the price in the ‘Comment’ field instead it remains

So unless I’m misunderstanding the purpose of said ‘Price’ field somehow, its broken?



p.s. While I’m here how would one add a retailer to the drop-down list? I can see three I use often that aren’t included just off the top of my head: Brown’s Books, Hit, and Planet of Entertainment

EDIT I know realise it appears to be not saving because I entered a currency symbol. Still seems not right
