Every selling venue online has a place for you to input your shop policies in some way. So what sort of thing should you include? This is a little questionaire to give you a starting point in writing your policies. However it is only a list of questions, you'll need to format your answers into your policies yourself.
What is your shop name?
What do you sell?
What is a brief description of what you do?
What forms of payment do you take? Paypal, Google Checkout, Check, Money Order, etc?
What is the timeframe must you be paid in before you cancel a sale?
Do you require payment in full before shipping? (hint: this should probably be yes for your own safety)
Do you live in a state that charges sales tax? If so what is that sales tax rate that you have to charge to orders in your state? (If you aren't sure, look it up you don't want your state's revenue service mad at you)
How quickly do you ship? Next business day? Only certain days of the week?
What shipping service do you use? USPS, Fed Ex, UPS?
What type of shipping do you use, is it priority mail or ground shipping? Does this vary depending on product?
Do you offer international shipping? Which countries?
How do you handle international shipping? (Make sure to state that recipients are responsible for any custom fees or taxes in their country)
Refunds and Returns?
Do you take returns at all?
Are there limitations to returns? Do you accept all returns or only items broken in shipping?
Do you give a refund for returns or replacement only?
Do you offer gift wrapping? Is it free or for an additional fee?
Are there age limitations for your products? Why?
If you sell edible items:
Does your state require a licenced kitchen? Do you have one?

If you sell Bath and Body:
