That is probably the worst item description ever by Currys (not having a go at you) (lol) They manage to mention both the mini 4 and the Air 2 in that in various places! Anyway, it wouldn't suit the person who asked as the mini 1/2/3 are a different shape/size to the mini 4 (thinner and taller).

Google Currys clearance, sort by price and have a look through! Cheers Nask https://www.currys.co.uk/gbuk/search-keywords/xx_xx_xx_xx_xx/-clearance-/1_20/price-asc/xx-criteria.html
I think that case is more for the ladies, are there any others on there?
