I asked for 2 of these glow plugs http://www.horizonhobby.com/Products...ProdID=HAN3001 for my new Alpha 60 , which i also got today, for my birthday. Anyways, I open the box with the glow plugs and I find 2 sleeves of glow plugs (12 each). I asked for 2, like in just 2 plugs. Whenever i bought plugs for my trucks they came as one is one plug. At a price of $6.49, I cant imagine thats for 12 of them. So I went to make sure they were ordered right, and on the invoice it says Order Qty: 2. $4.99 each. Total of $9.98. So im confused. are the plugs like 50 cents each or did I get $120 worth of plugs for $10? Thanks
