I think it's the seasonal demand plus a tremendous influx of new beekeepers and beginners which has placed quite a burden on the suppliers.
I've tried to order on-line, but it was too challenging for my patience. The "search" feature on many of the sites is limited and I can't find what I am looking for. I much prefer to pick up a catalog and talk to a live person on the phone who can give you instant feedback.
After a couple of hard lessons in my early years, I got in the habit of looking at my needs about six months in advance, then ordering during the off-season and keeping plenty of extra supplies on hand for expansion and newly caught swarms. Winter gives me the ideal time to assemble and paint equipment. Spring and summer are just way to busy with the bees.
Also, I like to place my orders with the vendors who show up to the national and state meetings. Almost all will bring an order with them for me to pick up without incurring shipping charges.
At every meeting of our local bee club, guys are asking, "Hey, I'm headed over to [supplier], does anyone need anything I can pick up for you?"
Shipping charges are a killer.
