You know me, the data stuff makes my eyes glaze over, but I have picked what I understand.

CON > More paper wastage in the long run because I put bubble mailers in the envelopes anyway (unsealed so they can be reused, at least)  Could you use scrap paper/tissue ? rather than bubble mailers

CON > Much higher outlay to pre-purchase enough envelopes to last at least 2 weeks at a time  If this became a permanent thing would Bulk buying assist in lowering costs?

CON > Lower revenue  Could this also be attributed to the changes at eBay ATM?

Not a business person in any sense of the word any more, and certainly not on eBay, but just pondering
