Buy Me ‑ Sticky Buy Button

This is a great app, I have now installed on 4 sites. It provides lots of useful features including the best quick buy app I found - that works well with variations from the category page, search box and anywhere products show up. The app looks great, you can customise it to fine detail and works nicely. Importantly the support is EXCELLENT, they are very helpful and really go out their way to help customise to your requirements. Totally recommend this app.
