Question details

Take in consideration prior to this question I have done benchmarking in prices.

Ok so im selling this product that happily costs me to produce about $5 each piece and I’m selling it for$8 each piece to stores in which I do free delivery too since I deliver only here in the state area. I make delivery amounts of $350,$500, and even $850 daily with some of them paying net30 and others instantly... But is very stressful to make this as I also pay my only 3 workers individual$400 a week for 10 hrs each day but hence they do indeed produce me about 400 pieces a day.

My question is;
1)Am i selling it to cheap?
2)Should I Eliminate a factor : Free deliver?
Net 30 days?
To much employers?
3)Never make them by a amount of $500 or less? Because customers want more and more as they keep calling me but then again I don’t know if I’m making enough profit for my$2000 a month expenses as I feel I should be making more money even though Is carrying me for a living as of now.
