The only complaint I have is the amount of emails they send me. I didn’t opt into emails on my first purchase but received them and unsubscribed. My second purchase, I specifically made sure I chose to opt out. Before I was even through checkout I received an email alert on my phone. After checkout, when I checked my email, it was from sweatblock (even though I opted out) and was a 20% off coupon which I could have just used at checkout, but it was too late. So it’s a bitter sweet thing because I didn’t want emails, I got one anyway, and yes it was an awesome coupon, but I didn’t even get to use it.
