Hi there! Here are links I use for all three - the savings really add up. The clear bags are similar to the SU ones. I went to the store when I bought them to make sure they weren't simply plastic bag types. Then I ordered them online on sale once I saw they were the right ones!
Mono: $1.85 each - Free shipping on $45 purchase. (They have all different types - this is just the link to the refills)

Envelopes: .05 cents each. I typically buy 1,000 at a time. This is 25 lb weight.You can buy these in smaller quantities too. The cost per envelope decreases with the larger quantities, which is why I buy so many and just stock up on them. I also buy the thicker envelopes for my special people

I also google coupons for all 3 companies before I place an order and can typically find something to take an additional discount of some sort.
I hope this helps!!! I make cards in bulk too
