Questions about Reusch Attrakt Fusion Guardian AdaptiveFlex Goalkeeper Glove

Hello Galaxus, I have noticed a very unusual pricing for the goalkeeper gloves. Last Friday they were in the shop for CHF 86 (only 1 piece available), on Sunday they were shown as no longer available for order and now one piece is available again - but for CHF 150. Can you please explain to me how this pricing comes about? To be honest, it seems a bit dodgy to me. Kind regards
