Buy Button channel

I've been using this app for years, and I finally have to point out that it's a very faulty app. When I add the code to a blog page, and it looks fine, I come back to the page months later to optimize the page, and the code is altered or not working. Really unreliable.

The buy button has two main shortcomings. The first is that there is no way to add the cart on the side of the page to a whole website. It only shows up on pages where there is another buy button. So if you had a Wordpress site, the cart button will not follow the user as they navigate.
The second issue is a bigger one. If your customer is in the cart and clicks the logo to go back to the full shopify page, the cart contents don't follow. So a person might put a few items in the cart on a Wordpress site, click the link to the storefront, then have nothing in the cart. They might shop more, not realizing it, and purchase just the additional items.
It does work really well, though for products. The cart link on the side of the page is nice, it is well designed, and it is connects with other products on the same site really well.

This is a wonderful app, and with the help from the Support Team i was able to edit it the code for my requirement wherein i wanted the buttons to redirect to my website product pages.
