I&#x27;ve had my first two annoyances with amazon, after years of having zero.<p><pre><code>  * Add on items. Can&#x27;t buy them on their own, can&#x27;t buy more than five. What&#x27;s going on with these? Just let me buy them in bulk. 
  * Recently, I had an item that was prime, but wouldn&#x27;t ship to a PO box. I&#x27;ve never had this – amazon always chooses USPS&#x2F;Canada Post for PO Box orders. The item was small. I had even ordered it to a PO Box before, successfully. I was able to complete the order to a pickup point, *at* the post office, just not in my PO Box.

These are trifles. But the reason I buy everything at amazon is that they removed all trifles. I&#x27;ve been noticing more of them recently.<p>Of course, on the flipside, amazon.ca has massively expanded its offerings. Which is great. However, many of them are not sold by amazon&#x2F;shipped by prime, and it increases cognitive overload. I have to calculate shipping, deal with third party merchant shipping emails&#x2F;review requests, sometimes they don&#x27;t ship to PO Boxes, etc.
