Walmart offers the PBS Retro Space-Themed Virtual Reality Headset for Android / iOS with PBS Lunar Base VR App for $7.99. Opt for in-store pickup to avoid the $5.99 shipping charge. That's $17 off and tied with our mention from three weeks ago as the lowest price we could find. It works with phones 3.5" to 8" and features dual headphone slots, space-themed stickers, and a simulated viewing distance of 1,000" at 10 feet.
Some chains have retired their senior discounts. But these grocers still have deals for the silver-haired set.
