I have only ever used SPS for my stacked cakes.
Now, I have nowhere locally to buy the pieces so I have had to order them online. It's worked fine except the cake I have this weekend- the company continually sent me a 12" plate when I ordered an 8".
Anyway, I'm freaking out a bit, as I only have 6" separator plates. I ordered an 8" last week from another company and paid extra for expedited shipping but alas, it is now saying it won't be here until the 16th.
