This has been tried before, but I want to get a pair so I'll try this time.
Protectear is a Surrey-based company specializing in molded silicon ear plugs, their normal prices are ~$140 a pair, with 11 or more, we get them for ~$110.
Go to their website to check out all the different types of plugs you can get,
All plugs come with a 30-day fit and 3 year defect warranty.
We would need to go as a group for the molding, at least 5 at a time, and it needs to be in north delta/surrey. He is cool with doign it in the evening or a Saturday if it's worth his while.
If you wish to talk to the saleman personally, his name is Stephen Crock at 604-240-9441, and just reference my name, Geoff Lenahan, when talking to him.
Please PM if actually interested, I want to get a pair in the next few weeks.
