Is there some type of return fraud going on at the moment that I am unaware of where materially different low value products are being returned, seemingly through a third party?

Its very rare we receive returns but of late there has been a spike, but there was also an increase in sales so we did not think much about it, until one of the returns arrived.

We only sell gardening supplies so receiving a little notepad back as a "return" really stuck out, so we filed a Safe-T claim and were taken care of (Thank you Amazon) We thought that was the end of it until we received another return today, and you guessed it, it was another little notepad, identical to the last in shape and size but with a different caricature on the front. We do not carry, stock or resell these little booklets

Order #1 was shipped to SALEM, OR 97304 and Order #2 was shipped to GALVESTON, TX 77551.

Both returns packed in the same size mailing envelope, both return labels printed on a professional 4x6 printer, both returns SHIPPED FROM CA (Not even Salem OR or Galveston TX where the original orders were shipped to) and both products returned are identical little notepads with different faces on them.

Got a very threatening message at 2AM this morning for the second return as it arrived after hours on Friday so we did not see it until we got to the warehouse this morning. Just responded saying we did not receive the product we shipped and will happily issue a refund once we receive our original product back.
