Did your PriceWaiter button recently disappear when you changed your theme in Shopify?
Unfortunately each time you change themes, the custom PriceWaiter coding is removed on the backend. To re-install the button on your product page(s), go to your Shopify admin page, select Apps, find the PriceWaiter app and click App Preferences.
You'll see the check boxes for Enable Button and Auto-Install on Product Pages. Uncheck and re-check those boxes and then Save.
Voila! The button should be back on all the appropriate product pages.
