Hard to Find Publication Easy to Get from American Nautical Services!

I've purchased and used copies of the "US Naval Observatory's Nautical Almanac Office & Her Majesty's Nautical Almanac Office" joint publication: Astronomical Phenomena for the Year - - - - for decades. I watch the US Government Printing Office website "like a hawk," to ensure getting a copy every year, but the past two years that has not worked. I found a copy of the 2024 edition at a retailer in the U.K. last year and bought it from them (for US $30) it retails in the US for $14). In desperation again this year, I looked around and found American Nautical Services. They had the 2025 edition for $19.95. I didn't blink, but bought a copy in a heartbeat!! Better still, the publication arrived three days later. Sweet! Thank your American Nautical Services - for having the product I needed (desperately) and getting it into my hands in a flash!
