Oh, about the almond flour ... yes, quite expensive. However you can freeze the remainder, and it will last a long time. Or, if you have the apparatus to vacuum seal things, you can seal it in a bag or jar - still might want to freeze or refrigerate though. When I started low carbing i went looking for baking recipes, and used a fair bit of almond and coconut flour. After several years I don't feel the need anymore, and a pound of almond flour lasts a long time. I think you said that the sweets aren't that big a draw for you; I am the same way, so my baking efforts are mostly experiments to try and convince DH that eating this way isn't total and complete deprivation. So far, it hasn't worked well :-)
Coconut flour isn't difficult to make yourself; let me know if you would like directions
