I just got this email from Eversave:
We’re very sorry for the confusion today regarding the ToysCamp.com Save. There were last minute changes to both the price and the shipping details. Heidi and I weren’t aware of these changes until this morning. The deal price had decreased from $12 to $10, but the voucher could not apply towards shipping.
We’d be happy to give refunds to you or any readers who are disappointed with these changes. Please feel free to have them contact email@example.com. I will keep you posted if anything else changes.
