While working I would do a few loads during the week after work.. I refuse to give up weekends to wash clothes .

When you collect your mail.. Immediately take out the BS and throw away right then.

Use synthetic Oil in your car much better and last damn near twice as long mileage wise.

During the week while your doing a load of wash,, Pull out what clothes you will wear the next day.. While doing so if you come across some clothing you haven't worn in a long while , Toss it in a bag hanging on the back of your door, keep adding things nightly or every few days. Soon you will have a bag full of clothing to donate and it wasn't a real chore to do so.

as for returns .. Set alarms on your phone for 1 week from purchase... By then you have mostly likely tried the item on ..it will fit or it wont.. Staple the reciept the the tags that hang off new clothes .. Can't lose them that way.

again use your phone for alarms to return books or audio to Library.

This is just me , what I would do if i had your list

Walk in the door with mail , sort it , toss it or keep the bills.
Gather clothes for a load to wash and dry, get thoses started .
Feed kitties and go clean there litter box.
Pick out clothing for the next day. look for something to donate
Put clothes in dryer
Eat dinner , exercise, relax... whatever
Take out dried clothes and hang or fold then .. Takes only a few mins. I promise.
Decide what clothes your wearing the next day and have them ready to go.
Right before bedtime set out your skin creams for morning

I can tell you for a fact that if you include all the "actual time spend" doing these thing take less than one hour.

Use your timer function on your phone Hammy

Seriously this is going to free up a lot of time for your weekends to be fun not labor intensive.

I have a bunch of other tips if your interested
