1st Ex? As in there's another Ex?
If so, you're a braver man than me...this one (marriage) is going on 31 yrs now, but if it ever ends...I have to pray that if there is indeed a heaven, fornicators get in.....very doubtful I would be getting married again.
Amazon...admittedly I'm still a fan of some brick and mortar shopping, but I use Amazon quite often. A lot of my golf stuff, I've gone direct to the sellers instead of through Amazon because I get access to their entire online catalog.
That said, Amazon is not always the best price...I bought a pair of Smith Optic sunglasses and surprisingly, REI had a better price by more than $10 for the same model.
