This is my first Grand Slam. I am Canadian. I don't know why, but I was surprised that my partner was more into it than me once I explained it to her. I just wish I hadn't started with 8 days before the promo ended. I could have got some cheaper (and free) hits. I basically had 0 DM and created an account too late to buy or share miles (or get the magazine credit on one account).
I have 8 hits posted already and when all is said and done, I should have enough for the 20 hits with a few safety hits. I am confident most of them will post, but I don't enjoy wondering about some of them (i.e. Shopping Mall).
