Coins to mystery box back. How long will it last? What have you gotten?

Sisterbear

I have over 5 million coins so I was happy to see the coins for mystery box pop up. Any ideas how long it will last? I am getting the same 6 prizes over and over so I didn't know if I should hold out and try later or just blow all my coins since they are of no use to me.
I have been getting 1 gold, 20 supplies, bob lugman, fast flo, Patti, over and over. I also have gotten 11,111 coins but that isn't really a prize, just another chance at a box.

Also is everyone getting the mystery box? My husband didn't have the option on his ipad.

Well I guess I'll answer myself in case anyone is looking for an answer in the future. The mystery box last about 30 hours. I was able to spend about 2 million coins, got 232 gold and way to many tiara prep recipes I can't use, got 6 fast flo, 140 supplies, and maybe 6-8 patty or bob recipes.
Glad I got some of the coins spent and some gold but I was really hoping for some of the many 4 hour prep recipes that are needed for the new levels.
