Here are a few low price bedding I found and you can also save more money by getting your items shipped to you local store for free.

Disney Baby Pooh Set 4 Piece $39

Seed Sprout 4 Piece $67

Chelsea & Main 4 Piece in Blue and available in Pink $47

Garanimals 4 Piece $25
Mattress is another one that you can get a great one but pay an arm and a leg for something you'll be using for only a few years. I might sound like a cheap ass to you but again babies grow fast and they are pretty expensive if you don't watch your spending. After doing a search for mattresses and searching at the store, I found IKEA for having the best prices for new product. Prices start at $34.99 and up to $89.99. You can also find gently used mattresses on Craigslist.org.
