LOW, LOW COST , LOW COST, OR MORE EXPENSIVE?
In life you have (too) many choices to make. Here I've saved you from more choices!.
I give you the LOW LOW COST OPTION or the FASTER BUT STILL LOW COST OPTION
If you buy ONE or TWO (or TEN) items the cost to ship is $3.99 and your purchase will be sent by Media Mail for books (or first class in the case of strings, reeds, etc. that don't qualify for media mail). This can take from 3 to 7 days---sometimes faster, sometimes slower---depending on your location and how the Post Office feels about delivering your items this day (week?).
FASTER SERVICE, ANYONE?
If you want faster delivery--Priority Mail in two to three days--there is a small "upcharge" for the higher cost of delivery. This charge is an extra $6.00 for a total of $9.99, and again, for any number of items. Or, you can go the UPS route which is more expensive and often slower than mail service!
That is about as simple as I can make things for you.
ALL methods come with a delivery confirmation number that the PO may (or may not) actually scan for tracking purposes--UPS always scans! I email these to you as soon as they are shipped.
