Feb 18/issue #12's ToC is out; what does Kubo have to say?

"Higashimaru no shain-san kara kyarashiiru nado itadaita. Futsuu ni oubo****eru kara ureshii!"

He received chara seals from a Higashimaru employee. Because he usually... subscribes(?), he's happy about this!

Alright, so Higashimaru looks like it's a food product company (primarily soy sauce, but other stuff too). Chara seals look like these stickers of mascot characters. Presumably of characters found on this page: http://www.higashimaru.co.jp/product.../cm/index.html.

The verb in the second sentence literally means subscribe/apply, but that's throwing me off a bit. Perhaps it means that he's a frequent customer? Or would it make sense that a person can 'subscribe' to a food product company? That is, would it basically be some paid plan to get regular deliveries, or something?
