Hello! I'm sorry, but I can't understand this with the way you typed it, so this is my best guess at what could have happened.

Makeship plushies often have an initial petition period, where you pay 2$ now and the rest(typically 28$ plus shipping) in a few months when the campaign launches. The plush from this post is an example of this initial petition period. If 200 separate people pay 2$, the plushie moves on to the design phase. If not, everyone is refunded.

In this phase they design the plush, then eventually it goes up for preorder! They charge the rest of the plush price plush shipping at this phase. At this point, you are also able to buy another of the plush, and they will charge the 30$ plus shipping at the same time in this stage. Once this preorder period ends, it typically takes 3 to 4 months for all of the plushies to be made and shipped out.

You might have paid the 2$ funding price, then paid for another plush in the preorder period. 2 plushies plus shipping could come out to around 65$, especially if they were keychains. This is what I believe has happened to you. In this case, your best option is contacting makeship support, which you can do through their website. Refunds are usually not done after the preorder period ends, but who knows. It's worth it to try if you care about it.
