@Pedigree I think he's referring to the latest purchases section that can be seen here. Anyway, to answer the question, I think those two are playing around with a possible shop feature, as people on MFGG try to figure out ways to make the coins have more use (since right now, coins can only be used to donate to others, which doesn't really have any impact if nothing else can be done with those).
