I seldom order on line / but won't say never. I do go to the big box stores but mostly I buy at gun shows.
compare these prices
Guns show Varget $23.00 LGS $29.99 or more
Gun show primers $28-30 per 1000 LGS $4 to 6 a hundred
bullets are tougher thats where on line is cheaper but freight must be considered.
Don't be bashful when I do godd to a LGS I ask them if they have a discount for big loading orders. Most of time they will work with you. Hey 10% of a $300 order is another 1000 primers
