Thank you so much for taking the time to answer.
Again, many thanks.
Have you ever thought of including the shipping price in your item listing? It might eliminate all the customer shipping uproar.
I don't calculate dimensions when I wrap an item I just try to make sure it is light as possible. You will most likely get charged for only the weight anyway when shipping only in the 48 U.S. mainland states anyway.
First class shipping is useless without tracking because a customer can lie about not receiving an item and that's a mess and a waste of time. So tracking is a must always.
Combining shipping....in the listing will only work for flat rate boxes not wrapped paper items. That's when the flat rate shipping is of any real use. With us clothing sellers it comes down to the art of folding clothes for more room in the box or envelope or 3m wrapping paper. The small the fold the more money your likely to save. If it is something with heavy fabric then rolling it then packaging is a solution.
For example someone buys 2 shirts 4.95 + 2.50 extra shipping.(supplying you can fit 2 shirts in 1 envelope)
Depending on the clothing size and fold is going to matter when shipping multiple items too, like you can save by shipping two sweaters folded or rolled very well in the medium flat rate box(the rectangle version) and ship those for 10 bucks opposed to the paper method which would've cost me 7.68 x 2=$15.36
Another idea for combined shipping is to mention that if a customer spends x amount of dollars or buys a certain amount of items in that 1 shopping transaction then you will ship the items in a large flat rate box. Or if that's not enough and the clothes does not fit it would be smart to ship UPS then. It's better to use a bigger box and spend 15 bucks for 10lbs and location than use usps $15 large flat rate box if the clothes can't fit.On top of that ups gives you a tracking number for free.
try it i hope this helps or get some juices flowing.
