On 8-2 over 100 reviews of thredup were posted instead of the usual 4 or 5. Over 90 were 5 stars. You connect the dots. I have been told this happens anytime the overall rating goes below 3 stars.
Now in addition to 6.99 for shipping, you will have 6.99 charged for recycling if 1 or more items are rejected. So you start $14 in the hole.
Are these the actions of an honest business?
