I have been noticing the change for some time. A long time ago I used to get it all in one heat sealed bag with all the parts in a heap. Slowly over time I have noticed smaller and smaller baggies. I have had some orders come with everything individually in tiny zip-lock baggies. I have had some orders where half the order was in one big heat sealed bag and the other half in seperate sealed baggies.
I have had errors in every single order. Missing parts, wrong quantities, parts I did not order, etc.... It is never a big deal, I just call and they are glad (well maybe not) to remedy the situation.
To me it really does not make a difference as long as I can get the parts. I would prefer that they do what ever get the system efficient so the prices can stay reasonable and the effort, on both parties, is low.
