I've watched about a dozen or so episodes so far, it appears that the house minimums around this time were $300 for an IUFB, $1000 for the total ARP for a pricing game, and $5000 for the Showcase. Just like on many home games and in other eras, if you keep watching/playing, you'll come up with the same products/prizes again, helping you to hone in better on your pricing skills like a good ol' LFaT. Just don't bring in a newspaper like an audience member near where Frances was called on down from 4611D was holding. It certainly didn't look like a staffer who may have used a newspaper for the GPs in Now... and Then.
PS My earliest personal memories were around Season 16 summer reruns where I could faintly recall some episodes with dark hair Bob, some with gray hair Bob with the pink Pricedown Big Wheel walls, and some with the then-new Super Ball-style Big Wheel walls. Since I was just a preschooler/kindergartener for the next three years, those reruns will still seem very fresh since I was still too young to really appreciate what was being offered, not to mention that very few episodes from the seasons in the high teens were ever rerun by GSN. I still have my personal notebook with a mock Check Game from 1990 that speaking of misspellings (check out 4611D again), I wrote VOID as "VOLD". Speaking of which, you'll also see that the VOID stamp was a lot stronger then compared to today where it seems like over half of each letter is missing.
