Hello.
For one, I didn't see any products under Aquamarine Angel.
I clicked on Bengal Tiger, and I saw a page full of products, but they all have white backgrounds. Try adding some background colors to your products to offer more variety, plus people want something that's not quite so plain at times. White can be very plain, depending on what it is. Use the tools on your create page to find the colors provided by Zazzle. It's to the right of your page when you're designing something. Just take a moment to play around with those tools. You can always delete the item you've practised on, then again, you may like what you see and want to sell it.
Put some text on and inside your greeting cards. People want to buy cards for special events, so a birthday card with at least "Happy Birthday" and a greeting inside would work.
Make items that are customizable by way of templates. If a person saw a mousepad with text you put on it, but wanted to change it to put their name, you should make sure to have it set that way.
Here's how to do that...
http://forum.zazzle.com/create/how_to_allow_customers_to_change_text_images_see You really need to stop breaking up your tag words and make some phrases. Tags are what get your products found during an internet search, and if someone types in "closeup of a bengal tiger", your item won't pop up. You have - wild, animals, africa. Make that a phrase - "wild animals of africa" so when someone types that in, your product has a better chance of showing up. If you wanted a mousepad with a palm tree and ocean waves, you wouldn't just type in "tree", would you? Be specific in shopping and in selling.
Make tag phrases by putting multiple words in quotes "like this" or by connecting with plus signs like+this.
How are you advertising? Are you using Facebook, Twitter and other online setups? Have you been passing out business cards and flyers? Have you visited the Promote section of the forum to see if someone will advertise for you? Give these a try if you haven't already.
A few other notes, but not about selling....
You really don't have to put so much detail into your description about the iPad case with the tiger. I do encourage adding more details...something more than "tiger", but just a few words about the colors of the tiger, the type of tiger...something like that will be good. Then again, I've heard that most shoppers don't read the descriptions, but descriptions can help get your products found just like tags and titles.
You should add a banner to the top of your store with the store's name in it.
