One thing you have to keep in mind is that Auctiva covers both the sale price
AND shipping. So your designer sunglasses that start at $49.99 will actually be covered at the $50.01-$100 rate, which is currently $1.70 (that's what Auctiva will charge you). If you don't mind taking a small hit on the insurance, then you're OK. Otherwise, you need to change that. Most sellers would charge the buyer $2.20 for insurance in that price range.
Also, at the far bottom of your ad where it states the Shipping and Handling info, it says shipping insurance is "Not offered". When your customers check out, they will not have the option of adding insurance to their purchase. If you want your customers to be able to buy insurance during checkout, you need to fix that.
One other thing to note. You state in your listings:
quote:
I cannot be held responsible for an item if it disappears, breaks or if it gets damaged.
Be aware that, if a buyer complains about non-receipt, or damage, and has paid by PayPal, the buyer can get reimbursed whether they paid for insurance or not. I don't know how much of a fraud risk designer sunglasses are, but a savvy scammer can cheat you out of your money
AND product fairly easily. It's a good idea to insure any package that you cannot afford pay for if it gets lost, or the buyer files against you - even if it's at your own expense.
Regarding shipping, I think USPS is fine for small light items such as what you're selling.
