Hi Robert,
I have looked at your site and can see that the product is not holding the Sale Price after being added to the Cart then navigating to another page and adding a Product from another BuyNow module.
I have not however, been able to replicate this issue on our test portal with a similar setup. I am testing on www21 on the latest version of the Cart soit is possible this issue may have already been addressed in a recent release.
Please confirm that all of your Featured Products and MiniCart modules have the same BuyNow Page Name configured in the module Settings as I believe that you are using quite a few BuyNow modules.
I have setup the following on the test site, please advise if your configuration differs:
Featured Products Page - http://www21.smith-consulting.com/en-us/featuredproducts.aspx
Use MiniCart enabled
Add Product with Sale Price to Cart
Product is added to the MiniCart with correct Sale Price applied.
Navigate to BuyNow page - http://www21.smith-consulting.com/en-us/store.aspx
MiniCart module added to page
Use MiniCart enabled
Add a non Sale Price Product to the Cart
Product is added to the MiniCart with the correct prices with Sale Price applied.
To confirm the issue is fixed in the latest version of the Cart you can download the trial version to upgrade to the latest build and fix the issue. Be sure to make a full backup in case you need to rollback.
You are also welcome to login to our test site to replicate the issue. This will determine if the issue is with the latest version of the cart or an issue with your specific dnn portal/cart install.
