There have been several times that the "best" picture on a particular roll of film has been at one of the ends. When I used to shoot slides, I'd get 1/2 or 3/4 of a beautiful picture and the rest would either be black or transparent. I later found out that most professional photographers actually skip 2-3 frames at the beginning and end of the roll of film so that they don't run into this problem. That used to make sense but, with the way film and processing costs are going these days, it's tough to "throw away" a couple of pictures per roll. But, that's about the only remedy for the situation. As long as we keep trying to squeeze that extra picture or two out of a roll of film, there will be times where it will backfire.
My experience with Kodak via Target has been that they'll print whatever they can and will charge you according to how many pictures they print -- that is, when I actually have 25 pictures come out on a roll, they'll print all 25 but they'll charge me more than they would if only 24 had been printable.
One common practice I don't like -- they always charge more per print for a "reprint" then they do for an initial print. So, if they don't print a picture because they thought it wouldn't come out, it will cost you more for the "reprint" than what they allowed in the 1st place for the original. I got into a big fight with a mail order processing place over this several years ago. They knocked off 15 cents for a picture they didn't print. I looked at the neg and it looked perfectly good to me. I sent the neg back, with a letter explaining the situation, and the 15 cents back. The printed it (as I predicted, the result was excellent!), sent me the picture but also sent me a bill for 10 cents. I refused to pay the 10 cents. They even threatened legal action when I refused to pay!!! Luckily, this all occurred while I was in England and by the time they got to this point, I was safely back in the good ole US of A

. BTW, this happens a lot with low light pictures (sunsets, fireworks, moon/star shots, etc.). If you know you have low light pictures on the roll, it's best to note that on the envelope when you turn the film in so they can take that into account when doing the printing.
