I don't know why they have that part of the process covered but not the initial procurement.

Because the cost to Google if they don't is huge: credit card chargebacks are very expensive for the vendor. Then there's the PR cost of having hacked off customers complaining all over the net about receiving broken goods and being given the run around by Google.

Far better not to ship anything at all than to ship something broken and then refuse (by inaction) to do anything about it.
