So far, I've been using different offers to get stuff. I usually get an email around once a week with different freebies. The UK site will only allow you to get 4 free items per order, so, as my wedding is still almost two years away, I just get 4 items each time and then wait for the next email to come. I think I've seen people on here use the same email a couple of times though (i.e. if you're only allowed 4 things, but you need 8, just do 2 separate orders), so that might work, although there'd obviously be 2 lots of shipping to pay.
