Hi Jeanette,

Q: The six month subscription cost $29.99 a month yesterday. Why did the price go up by $10 a box?Asked by Kathy S., November 2021
The price of the Matter box varies based on the duration of the subscription and any coupons applied to your cart. There are currently some promotions on our page that can get the cost of the box down to near that price for a 12 month subscription before shipping and tax.
Q: I have sent TWO messages asking where my box is that I ordered on Oct 1st! It’s now Nov 5th and still no box and no response from your company! I will give until the end of today before I cancel!Asked by Tammy B., November 2021
Your first box will ship in the first week of next month, no matter what day you subscribe. All boxes ship in the first week of each month.

Great box - I look forward to it every month. There's no other box like this - fun and educational. I can't wait to show my collection to my great-nieces and nephews when they're older.

This box is amazing. We got it for our son thinking it might be fun for a few months. He asked to renew it because it is so great. Opening it is a family event now. The box has contained some truly astounding and unique objects such as a piece of a Mars meteorite, NASA film, antique medical supplies, fossils, gems and pearls, historically interesting pieces....it is a joy to have a subscription box that is so inspirational.

If you are into science, and you want something purely unique, this is the box for you. Every item feels like an Easter egg. From space exploration to ancient poop (one of my favorite objects…) this is truly an amazing box.
