Guys, I got an email from Woo today stating the following:
Thank you for interesting in our products.
For BI3 we have a discount for only distributors.
but there are some end users asked the same question as you did.
so we decided to offer this for a short period of time due to we just
launched BI3s and wanna thanks for interesting to buy our first IEMs for
more than a pair.
You might buy 5 pcs,the price is 29 USD for each.
but we will ship it...
