You have to do some math to figure out what works. At $1.68 plus $0.12, your cost of goods is $1.80. Is you run that through a multi-tier pricing model (what's your gross margin, what's a broker markup, what's a distributor markup (this gets you to the wholesale price), what's the retailer markup, then you arrive at a suggested retail price. Once you can model this you can figure out if any quote is too expensive.
I just did this exercise for someone and put together a spreadsheet to work on multi-year sales forecasting and gross profit margin projections. I've taken out all the extra stuff and left just the COGS and markup lines so you can play with them yourself to see how they interact.
Note that Gross Margin is not the same as markup and I've done that calculation properly. Also, I've assumed a three-tier sales strategy just so all the costs of distribution are factored in. I've noticed that companies that assume they're always going to be able to sell direct to the retailer or customer get crushed when they have to use a distributor because they've never thought about what those layers would do to their cost structure. You can set the percentages to be whatever you want (including 0%) to see how changes affect costs.
For those who don't care to download the spreadsheet, a $1.80 cost of goods, 30% gross margin (you earn $0.77/unit), 10% broker markup (36 cents), 20% distributor markup (79 cents), and 100% retailer markup results in a suggested retail price of $6.79. Going from 30% gross margin to 50% gross margin jacks up the retail price to $9.50.
Of course you don't need all those tiers and your markup and percentages may be different. However, I'd work with this structure so you understand exactly what you're earning (or giving away). In the beginning, if you sell direct to the retailer you get to keep the broker and wholesaler markups, raising your revenue per unit to $1.82 (a 50% gross margin, which is pretty good).
