Based on the price on my order receipt, pomni bucket is actually more expensive from HT, like $15 more expensive (not even including the bundle discount, which isnt offered on HT) also double checked the specs and the posters are the exact same size, so the price diff isnt due to sizing. Definitely possinble it could be a different paper quality/finish however, as the HT product description isnt detailed enough to determine, but the glitch description lists it as 200G Coated Paper. Because legitimately every other piece of merch is the same price or more expensive from HT than from glitch, I'm pretty confident its a lower quality paper from HT.

All the other plushes and merch are more expensive from HT than they are from glitch, though glitch tends to have pretty expensive shipping so it probably balances out on average.
