Shipping rates is a killer for most of my products. We're kind of off topic here, but this may benefit Pex also, so I'll go ahead.
I can fit 3 5oz woozies in a SFRB for $5.95(I think?) at $6,99 each (yea, I know...should be $7...
..) that makes each bottle about $9 each. Most artisan hot sauce customers don't have a problem with $9 per bottle, they know it's small batch or small company.
The problem I face is I only have 1 real popular sauce in a 5 oz size. All the rest of my sauces are in 10oz woozies and 12 oz sauce bottles. One bottle of BBQ sauce weighs 19 ounces....without packaging! It can't go first class. It won't fit into the SFRB, priority shipping on that one bottle of BBQ would be about $8....more than the price of the sauce. The only way for customers to get a reasonable shipping rate is to buy several items and it goes into a MFRB.
The one item that does work for "shipping included" is the Pure Evil. The tins are light enough to go first class, I can work the $3.60 into the price, it's still at a good price point, and it makes it easy for the customers.
Some sites really tick me off with shipping. I needed to order some special retro-style light bulbs. Found them on a site for $3.99...and the site had a flat rate of $11 for shipping and handling! I KNOW for a fact they weighed less than my Pure Evil tins, should of been about $3. Ended up buying from a site that was $6.95 each, shipping included.
