Which establishes low value. So we’re not actually likely to wear them at all.
Given the cost I suspect that getting you to wear them is not the key part, they want you to discuss their product as you received a freebie.
Let’s change this.
How about, you hire a designer off threadless to make an awesome t-shirt that may or may not feature your brand and give it away.
You then provide two opportunities for conversation.
1) X company gave me freebies.
2) Hey I like your t-shirt where did you get it from?
3) You will actually desire to wear the t-shirt vs throw it out. (and thus allowing greater opportunities for discussion everytime it’s worn)
Give it a shot, why not? We all know everyone throws those t-shirts out anyway.
