Since Perfect Mix has priced themselves right out of my range I now use Lumberjack Comp Blend. $8.99 per 20lb bag at my local Rural King.
To be fair to Perfect Mix, the cost to ship 'piecemeal'/one or two at a time is expensive - more than the cost of the pellets. That is why buying in bulk, can save in overall cost. It can be a little extra to set up, but with a few pellet friends in your area to split the shipment, it is a great experience and cost saver.. As an added bonus, you get to meet a few pellet fans and talk shop with a few new friends..
Just thoughts...
FWIW.. Amazon free shipping- is not exactly free.. Shipping is included and combined in the price - hence free shipping - on paper. + if Amazon is 'reselling' they will add a percentage for their profit...
As an eye opener - wrap or box a bag of pellets and either ship it to yourself or a neighbor - it should be an eye opener..
