I noticed UP-FRONT LINK had a story about Tokyo Otaku Mode now selling H!P goods. They weren't a place I knew anything about, so I decided to check it out. I did learn a few things worth sharing.
They don't seem to have a lot of Hello! Project items available. It's not like they just have an H!P section of the store, but doing a search for Hello! Project there are currently only 17 results (+1 that is barely related). Still, it has some interesting stuff like pen lights, t-shirts, and towels from recent concerts. Or some things I didn't know existed, like a 24 page book containing the promo images for Taiki Bansei.
It may be a more convenient way to buy this stuff for those outside of Japan, but they still do mostly ship from Japan so shipping prices still suck. Testing with one of the pen lights, for example, there are three shipping options which come to $8.80, $12, or $18. It is actually possible to get free shipping--but you've got to buy at least $100 worth of items to qualify for it.
EDIT: Correction, they do have a Hello! Project section of sorts. Some of the items show a Hello! Project banner, which if clicked on takes you to a Hello! Project brand section with more results. Looks like they currently have 49 things listed.
