The following is an announcement from Stampin' Up!:

Please note that price changes will take effect on June 1, 2016

• Cardstock: Through the years, our quality of cardstock has stayed the same, while our costs have increased. After carefully analyzing comparable weights/quality of cardstock, we've brought out prices more in line with our quality, while still remaining comparable to other cardstock in the papercrafting industry
• Designer Series Paper Stacks: Last year we had to increase the price of our Designer Series Paper; unfortunately, at that time, we overlooked our 6" x 6" Designer Series Paper Stacks. The Paper Stacks are essentially our 12" x 12" Designer Series Papers that have been cut into quarters, so our costs for Paper Stacks are actually a little bit higher than Designer Series Papers because they must be cut and padded. Therefore, we're increasing the price of our Paper Stacks to be more in line with the pricing of our 12" x 12" Designer Series Papers.
• Bundles will now be offered at a 10 percent discount. Since first introducing the Bundle and Save bundles, we have increased the number of coordinating products offered in bundles and thus, in order to continue the Bundle and Save program, it is necessary to reduce the discount.
