Delivery confirmation no longer a valid defense against Amazon A-Z claim?

Today Amazon granted an A-Z claim for an item which had delivery confirmation. In fact, the customer admitted (via email) that the item arrived *after* she filed the claim, but didn't know how to withdraw her A-Z.

Amazon subtracted the money from our account, and sent us this message:

"Thank you for your response. Unfortunately the tracking information you provided does not include signature confirmation of delivery. As a result, this is insufficient evidence of delivery to the intended recipient. Note that many carriers, including the USPS, use a delivery confirmation that does not confirm delivery to the recipient's address, but instead only confirm delivery to the zip code."

So now *signature confirmation* is necessary for every order, or less sellers are not covered by the A-Z guarantee? Makes no sense, because the A-Z program is insurance that ever seller buys into! (that's what the $1.35 variable closing fee allegedly pays for).

Fortunately, this does not affect FBA sellers. FBA sellers have NO A-Z coverage. They continue to be charged the $1.35 variable closing fee, but receive no benefits.

Amazon deposits unreliable with Seller Central/Marketplace 2.0

Sellers on Amazon have funds automatically disbursed every 2 weeks. Or, they can access their payments through their seller "marketplace" account, and sweep their funds to their bank account more often.

However, since we've "upgraded" to Seller Central/Marketplace 2.0 (a requirement to participate in FBA), our deposits have been irregular.

We typically sweep our account every evening. However, it's been 8 days since a deposit has arrived. We started asking about it, and apparently they are not making the deposit, but adding that amount to the next deposit. It gets debited from our account, as if we received the money, then the next day it shows up as a credit again (as a "miscellaneous adjustment"). By the way, get used to these "miscellaneous adjustments" if you are on FBA - they appear on our account daily, usually as debits, and we rarely know what they are:

This revolving deposit has now been adding up over the past 8 days, but it won't disburse. We actually had to carry a credit card balance this month because we can't count on our Amazon deposits any more. I wonder if we can sue FBA for the interest charges?...
