Time to respond to some comments and add a bit more data...
BullseyeAlso worth noting that there has been a pattern of 2-3-4-5-6, IIRC. If you can figure out which number quantity goes with which item, and multiply each pair together, each total will be within $10-12.
This was false as recently as season 46--on the Feb. 13, 2018 playing of Bullseye, there was a grocery item (Good & Plenty candy) costing $1.29, which would have required 8 to be selected to get to $10. That said, I do agree that I haven't seen any case where there were two products that required the same number to be picked to win in at least a couple of years. Of course, this is tough to state with any certainty because they rarely show the prices of the products that weren't chosen.
Card GameOne other important point about Card Game is that the deck with the ranges is not shuffled before the contestant selects his or her amount. Since we don't keep track of where the selected range is in the deck, anecdotally I would say you should pick something from the bottom (furthest from the contestant) since they seem to like to hide the largest amounts down there.
Additionally, depending on what you've already drawn you have about a 30% chance to get something that's going to add $1000. Think about how finicky you want to be and if that amount is worth it or it will push you over your target.
Excellent point about the fact that we don't think the range deck is shuffled (though do we know with absolute certainty it's not shuffled before being brought out on stage?) I absolutely agree about choosing a card near the bottom of that deck and I've added it to my blog post.
What perfect timing! Yesterday was Card Game's 45th anniversary (7/4/74).
Awesome! I totally planned it out that way. Really, I did. (And if you believe that, I have a bridge to sell you.)

Check GameA friend of mine on Facebook suggested I look at various values of checks to see how often they would have won. I did that and have posted the results on the
Check Game page. Long story short, from seasons 43-47, the check value divisible by $100 that would have won the most frequently is $1900 (it would have won 36 of the 47 playings, for a win rate of 76.60%). Not surprisingly, $2,000 and $1,800 are just behind that, and then it drops from there. Now on to the Check Game comments here...
I think as long as the range remains $7,000-$8,000 the safest bet would be writing the check between $1,000 and $1,500. Even $1,500 would be pushing it. $1,250 might be the safest amount.
This season, the game has been played 10 times. $1,000 and $1,250 would each have a record of 4-6, while $1,500 would have a record of 6-4. Even better, $1,551 would have a record of 8-2.
I couldn't have said it better. For what it's worth, the best ranges in season 47 were $1543-$1570 (inclusive) and $1612-$1651 (inclusive). Both had 8-2 records. It's easy to look some of the playings with $6,000+ prices and get scared by them, but even in season 47, there were more prizes between $5,000 and $5,999 than there were prizes between $6,000 and $6,999. (The actual count was 6-4 for those keeping score.)
General commentsI'm a bit late in correcting this, but I honestly didn't read through the OP until now, so...
Unless it's in 10 Chances or Temptation. 
Some other car options I've noticed that tend to generate endings that aren't -0 or -5: "etch protection" and "auto armor". And from having built a bunch of cars (mainly for CSS purposes), I've specifically noticed that Hondas and Toyotas can have just about any other option cause a non-0/5 ending.
I'll get those games soon enough

. And yeah, there are a bunch of ways a car can end in a digit that isn't 0 or 5. I struggle with finding the fine line between "giving the reader enough good information that they can make the correct decision" and "giving the reader so much information that if they end up on stage, there's no way they'll remember it all in the heat of the moment."
I just want to thank you for doing this. This will be extremely helpful for potential future contestants.
Awww...thank you! My hope for this blog is that just one person will be able to say, "I was a contestant on
The Price is Right and I won because I followed a tip on Brian's blog." That would make this all worth it to me
