I made the mistake of trying the Same Day Unlimited free trial just before Christmas 2022. I did not cancel in time and was charged for the year and they do not let you get a refund. This is my bad and so were some of the reasons I found out the hard way that the Same Day Unlimited is not that helpful. I am in a metro area and near an even larger metro area, so I don't think I should see too many issues on availability, but I did.You need to make sure you clicked on the Same Day shipping option while adding each item to your cart. After an order arrived later than I expected, I realized this. So next time I tried to use this feature and I clicked the option, I found that almost all items I needed were not available for Same Day shipping. So it is cumbersome to use and not as useful as you would think. I think I'll keep my fee for using on the 6.95 fee the few times they area available to get that fast.
