Although the MSRP is similar between the 2, the xXx usually comes out quarterly and is usually fairly easy to find if acted on quickly enough. The BTL is an annual cigar coming out at the start of the holidays in most cases and not released in all markets. I have paid upwards of $18 for the BTL at my closest B&M that was fortunate enough to get them last year. Depending on how badly you want the BTL and how generous the person is offering to trade them up I would guess 2 to 1 would be fair if not slightly over the top. Just my 2 pennies as I have none to offer and no real leads as to who may have them. If I hear of anything I will let you know. :thumbs:
