A Foxco client has a Shopify store with too many apps which slows the site down (and of course they all cost some amount of money each month).

Because it's an alcohol delivery and gift site by law shoppers must be over 21 years old or older. Hey check out the site if you like top shelf whiskey, rum, gin, bourbon, wine, tequila etc it's called Sipsy.com :)

Many other sites require you to be 18+ for a variety of reasons. Anyhow, below is the javascript code with instructions on how to add it to your Shopify store. I've highlighted the areas in yellow that you might want to change. If you like this js please consider using Foxco.net as your redirect URL (too many people use Disney.com and they don't really deserve all those backlinks IMO).

If anyone requests it i'll make a lightweight wordpress plugin based on this with styling tools --- or you can just install the .js below yourself.
