I ended up going to two counters and picking up Pink Buttercream and Lavender Whip. I also intend on taking a look at Pure Decoration and Raspberry Swirl on a later date - the two shades were "like to have" rather than "must have" shades, so if they're still in stock the next time I go then they were just meant to be. I just HAD to have Pink Buttercream and Lavender whip.
I intend on having reviews posted by Sunday! Stay tuned!
