Travelzoo offers an Adult Ticket to Real Bodies at Bally's in Las Vegas, NV, for $19.25. (Groupon charges the same.) That's tied with our mention from two weeks ago and the lowest price we could find today by $9. This exhibit uses preserved human specimens to explore and illustrate different facets of human physiology. Book this travel deal by June 30 for tickets through the same date.

Of note, you can buy two Adult tickets for $35.50 (also at Groupon) or a Child's Ticket for $10.25. Those are the best deals we could find by $20 and $8, respectively.
