Ok now some of you are saying well wait a moment on my small server there are too many glyph makers and not enough buyers, what's worse players are camping the ah with their glyphs and fighting over every sale. The prices are below 30 gold for every glyph and 1/4 of the auctions on the auction house are glyphs themselves! Well if you find yourself in this unique situation then odds are neither method is going to net fabulous results. If you can, try to focus on the non-glyph methods for making gold as much as the glyphs themselves. Use sites like www.wowpopular.com to figure out the best glyphs to make and only make those, try to focus your efforts and save time. Also, check out when players are logging in that are your competition and keep a little spreadsheet so that you can see when is the best time to be up against the least people. One trick I use to post during prime time is to have like 10 of every top profit glyph and if someone undercuts then I simply repost without canceling. This buys me about 10 very valuable minutes where my opponent has to cancel hundreds of auctions, get them from the mail and then repost. It has proven a very effective method during prime time for me and if you are only posting around 100 glyphs vs the 200+ that other posters are putting out odds are they will consider not canceling their whole stash since 50% or less of their glyphs are showing up as red on qa3.
On my server there is a camper that plays basically the same times I do and I still made amazing profit by using the post but don't cancel method. Using a spreadsheet I was able to find the best times to post and avoid the vast majority of competition. Would you have guessed that 9:00 weekdays was actually the best time to post since my opponents did not undercut me until like lunch time? That gave me three hours where I was the only person with glyphs and the majority of my sales came from there and during prime time in the evening.
