Blu, I know this is not the answer you were looking for, but for future reference, here's my advice on buying avos:
Buy only Hass or Fuerte avos. No exceptions.
Take them out of the box yourself - not from a huge display where everyone has already "checked to see if they are ripe"
Buy them a week in advance - rock hard only. That way you control whether they will bruise or not. And don't dump them in your trolley with other stuff. Treat them like glass.
Keep them in a safe, warm, dark place - they will ripen in 5-7 days. Do not refrigerate whole avos.
Never, ever, buy avos with a shiny skin. They will be watery.
And if for some odd reason you only use half an avo, leave the pip in the other half and clingwrap it as tight as possible over the flesh - then you can pop it in the fridge.
