According to this blog post, Meta is doing an in-store sale on two of their more recent prints, Twinkle Journey and Old Rose. Old Rose is a classic-style print in muted colors, and Twinkle Journey is the infamous unicorn print.
Strangely enough, the Twinkle Journey items are completely sold out on their website, and have been for a while. I know the print is very popular among Western lolitas, and it seems odd they would discount it for local customers rather than sell it full-price to international clients. Old Rose is still in-stock online, and at full price too.
Then again, the blog does mention that the Hukuoka store is the only one to still have the Twinkle Journey print in-stock, and perhaps it's less expensive to sell at a discount rather than ship to the main office for webshop processing. Who knows? But if you've been hunting for either of these prints, the 30% discount will more than make up the cost of a shopping service!
