Here's the reason why you shouldn't order a custom cake from Wal-Mart, from the GinBlog:
Some people that work here had a going away party the other day for a woman that is leaving.
One of the supervisors called a Walmart and ordered the cake. he told them to write: “best wishes Suzanne” and underneath that write “we will miss you”. here’s the cake that was delivered.
