I keep the period set to 60 days,If I change "show" from recent to archived, I do see a bunch of old items. However,
the list starts with a bunch of items I'v just bought, should there be overlap between arvhived items and recent items?
If a seller removes a store listing before I recieve an item, does the item get automatically archived from my list of purchased items?
That could explain why I have seen items dissapear from my purchase list long before even 60 days is up.
Refunding the refund is a good point, although many of the sellers have specified a different account to make repayment to.
Imagine the effect of changing the feedback cutoff from 22(?) days to 1 week, people would have to demand refunds all over the place. Now imagine if it was a 90 day cutoff, everyone should have lots of time to leave feedback after their item arrived.
