I did think about mentioning if anyone was interested in one or the other, to message me and I'd make a decision whether to separate the set but I'm not convinced that's a good idea as the sets get a lot of lookers and they sell very well outside of eBay. (I sold two sets yesterday actually).

be very careful how you word this  as it could be reported to eBay as 'off ebay' transaction and get you a violation on your seller a/c
