I bought the cauldron at full price and got the hotdog on my second collection and have already had 1gem .i think it is worth it as there is still 10 days to go and I am getting at least 2 collections a day. The last two items from the fishing and mining are always in short supply and at least this way you have a chance at getting a decent prize. Even though it is now half price I don't feel hacked off about this. It is only a game when all said and done and it is only ?2.99in england for 120 gems . Hope you are lucky and get a dog!!!
