PM "sharkbike" on this forum. He's president of Harvard Sportsmens and Target and keeps them in stock. Since you will deal with shipping, you may also check out www.targetbarn.com.
I see what you mean. Checking the link that Rob supplied, shipping is almost 50% of the cost of the targets.
100 Targets = $70 and shipping is another $30
I bought a 100 pack of full size targets (paper) from midway for around $30. I patch the holes and can use them several times before tossing them. If you don't mind not practicing on cardboard.
Yeah, Harvard is kinda a haul for me down here on the shoreline of CT. Although, I'd like to check out a match up there later this year. I heard they do a great job.
