Nobody was in the least condescending. The reply was succinct and accurate. Not everybody feels the need to couch everything in smiley faces and cute comments to express friendliness, and doing without them is certainly not smug and condescending.
Also, not everybody does know about selling old magazines -- Ornament, which is pricey to start with and has historical value to artists on many levels, is a good example of one that can be resold, and if in a complete run for several years, maybe even for close to the cover price. (This would be to a collector who missed those issues or a library that needs them to fill out a collection, mostly.) Sunset (or more commonly, National Geographic) are examples of titles that might not have salability -- too common, too easy to get. (However, never hurts to try!)
I am a librarian. I once sold (to a commercial resale vendor) back issue computer magazines and some other kinds for $10,000. (Of course, the original subscription prices of a few of them were $300 PER ISSUE ($1200 per year, quarterly) so it's not so exciting as it seems!) People want to donate old magazines to us (in my current library) all the time (especially National Geographics) but we don't have a use for them, and in the end we'd have to pay a tipping fee at the dump to get rid of them. Nobody here has the time or resources to try to deal them on Ebay.
If I were trying to sell back issues of Ornament I would suggest bundling them by year. You could ask at a public library for referrals to a commercial vendor like I used, and they would make you an offer based on the run of issues available -- and pay shipping. Or use Ebay.
