I run an e-commerce store as a side-hustle: https://drinkyourdailywater.com/ We sell glass water jugs targeted at desk workers, to help remind you to drink enough water. I created it because I wasn't drinking enough water. Running paid ads has been very hit or miss, and I don't have a knack for the marketing. But word-of-mouth has been good for us and we get the odd corporate sale here or there.
this is pretty cool - if i could ask, where do you find a manufacturer to help you produce this? also, is fulfillment ran inhouse?
Fulfillment is done in house (I live in Toronto), and the warehouse is my basement!
Happy to answer any other questions :)
