Yeah, I bought the Deluxe Starter Kit from my meeting on Thursday. Been eyeing it up for a few weeks, and finally bought it. They're good value. It meant that I had the Eat Out Guide, I already had the Shop Guide as my free gift for joining WW, so gave my spare one to my grandma cuz she likes seeing what I can and can't have when she's cooking for me and I'm really enjoying the journal. I was keeping track online, but I much prefer handwriting things. I also got the pedometer which I've earned 19 points through wearing so far in 2 days, and about to go to Zumba and earn a few more.
It's definitely an incentive to keep on track though, as, like you said, you've spent the money on them, you want to make it worth your while. I'm like that with the gym. It's £40 a month. I pay half and my boyfriend pays the other half. I make sure I go as much as I can because it's a fortune and if I don't go, it's not just my money I'm wasting. So atm I've been going to the gym about 3-4 times a week, and going to 3-4 classes a week also, depending on my schedule. Classes are £5.50 a time, so by going to just 8 a month, I'm getting my money's worth.
