・It is only sold here.
・You can only buy this here.

「只在這裡賣」在英文中可以表達為 It is only sold here. 或 You can only buy this here. 。

It is only sold here. I will definitely buy it.
（這個只有這裡有賣。我一定會買的。）

This is a special limited edition item, so you can only buy this here. If you don't buy it, you will lose it.
（由於是特別限量版商品，所以只在這裡有賣。如果你不買，你就輸了。）
※ limited edition（限量版）
