*when more are realized, they will be added; share both the item and the poses you want joined
We realize that Gaia is bringing in money when multiples are bought with real money, but even if we get these joined poses there still will be users who buy multiples for whatever reasons. Not every user is willing to buy one item with real money (let alone multiples) for a virtual being they wish to customize. Then they have to resort to buying it will gold; the prices for some of these are expensive for just one.
For example, if one user wanted to have both the dark halos' west and east arches, they would need two dark halos. Dark halos are over one-hundred gold each. That one user would have to spend over two-hundred gold in order to acheive that pose combo.
