How do you folks handle shipping costs? Do you charge a handling fee? I'm just starting out with my business and decided to go with a flat rate of $10.00 for shipping but I can see that I will go broke soon if I don't charge more. Currently I'm using USPS flat rate boxes but because I offer 2fers or 3 fers people are generally ordering 2 lotions and 3 soaps which won't fit in a small flat rate box. Do any of you use UPS or FEDEX? I hate to raise my prices so soon but perhaps it's best to bite the bullet sooner than later. What are you all doing regarding this matter?
