That is some great work! Thanks for posting it.
I like the pizza slices best as well. Haven't thought about EXP Boosters or Birthday cakes so far, since they are too expensive to me.
Also the Pizza Boxes have some great value!
Haven't put much thinking into the other boosters so far, since as you point out, they are usually not really of great value for their price - at least at my level and in my opinion.
Keep up the great work!
Cheers,
