I hope this isn't annoying but Google brought me no worth while results so I thought to ask you amazing people!

I just signed up under the 5 a month and I know that in order to get a pin you have to do 10 dollars a month, does the same go for when the pins go on sale? Can any donor buy them or just the 10 dollar and up donors.

Will I have to upgrade next year to get the new bonus content? Or will I still get new bonus content if I stick with the 5 dollars?

If I'm doing the 10 dollar amount, after a year will I be able to buy the pins when they go on sale or will I have to upgrade to be able to buy the pins again?

Hope these don't get asked all the time, I couldn't find any concrete answers! Thanks for the help!
