Williams Coffee Pub: Free Drink!
If you join the e-newsletter from William Coffee Pub Canada, they will email you a voucher for a free regular size specialty hot or specialty cold drink just for joining!
You also get birthday gifts, as I mentioned in the past. I've joined with one of my email addresses, so I will see if the voucher can be shared, but it's likely to have my personal details on it.
