It's never too late to have ponies on shelves, right?
There are still some CP sets in a few stores here. The first set rainbows completely vanished...at least, where I was, but we've still got some CP ponies around. Hopefully by this time next year you have some pretty rainbows and unipegs in Aldi as well.
Such an odd place for them to be but so stoked for you that you found them
