i know they sells this at michaels but is i really worth it to buy the cricut ?
It really depends on you. I am a scrapbooker as well as an event planner so I will use mine for more than just cakes...so I bought blades for paper only and matts for paper only to go along with the cake blades/matts. So I use mine about once a week in one way or another. If you won't use yours for anything but cakes and you only make a couple of cakes a month then it may just be an expensive toy for you. But if you can afford the toy then the cost may not matter. For me it's a tool for two of the sections of my job as an event planner and caker so it was worth it for me to buy it. Is it still a toy, sure, mainly it is a toy. I could do everything it does with cutters or simply buy the paper fonts that I need but this saves me time and in the long run it will pay for itself. But that's for my situation. Yours could be very different. HTH
Only you can decide if it's worth it to you or not. I have both the expression and the cake cricut and I wouldn't trade wither one of them.
