Books are a very slow sell, and pricing is very important.
I looked up one on Addall,com and while it does seem to be scarce, most of the copies available online are one tenth the price you are asking. The high priced ones are leather bound reprints.
Here is your highest priced competition .

I find Addall a useful source for book information and for comparisons.
And 'check photos' is inadequate. You need to use your words. Measurements (not just size) on clothing and shoes in particular.
Shipping is often the hardest part of online selling. We often forget that this is just 21st century mail order.
Are you using the cheapest possible rate for shipping?
With that sock doll for example, all of Canada Post's parcel services include domestic Delivery Confirmation. If you have signed up for CPO's Solutions for Small Business

you can get the Expedited Rate at the same price as Regular Parcel. The SSB number is also used to get you discounts with Paypal and Shippo shipping which offset some of your packaging costs.
And consider your packaging. That strapless dress could ship in a poly envelope with a bit of tissue paper and a sticker for pretty.
