I feel for you. No one wants to put so much effort into their designs to have them not sell. I agree with some of the others in their opinion. When entering your site, I tried clicking on the designs to see them and then realized I had to click on the info tab. To some, this might be annoying. It was not user friendly immediately. I know there is a lot of things you have to keep in mind but sometimes we have to take a step back and think like a customer. It is hard sometimes because you know how your site works so sometimes you might over look things. The other thing I would change is when you do click on the info tab and are now into the design, the "yellow" high lite behind the font looks amateur. If you want to be taken seriously, I would definitely change this.
Your prices are reasonable but just wondering if they are too reasonable. When I saw that one of your shirts had a retail of 6.00 I believe, I thought wow, that's a bit cheap. In my opinion, I think I would raise them just a bit. There is a fine line between getting a quality shirt at a great price and a down right cheap shirt. You don't want to look too cheap. I am not saying that your shirts are not quality, but I perceived them to be cheap, in quality and price just on your price alone and perception is the KEY word here.
I do believe there is a customer for everything, and your designs are cute but is there a real value in them for the customer? I do understand that there are many people that love technology and their cell phone is everything to them but do your designs touch on what they truly value. Meaning, some people value eating healthy, humor, politics, inspiring words, wisdom, standing up for their rights as a race or religion, uniting race or religious beliefs, having tolerance for differences, or sometimes just down right raw humor which could be in the form that might be perceived raunchy, or all the way to the other side of humor that is respectable.
In my opinion, I think if you came at your designs in a different way you might have a better chance of selling them. We know that cell phones are important to your customers, but if we dig deeper, why are they important? They are important because they can text to anyone at any time, talk to anyone by just pushing a few buttons, get on the internet in a second, download anything at a moments notice, read emails instantly, etc..... And they possibly value these things because saving time could be very important to them, or they love to instantly gratify themselves with certain knowledge that is at their fingertips. Keep thinking along these lines and you will come up with many more reasons why they love their cell phones.
How can your designs reflect what it is that they really love about their cell phones? If you can touch on this point with your designs and possibly put a little humor in it, I think your designs would then be more valuable to those cell phone lovers and would prompt them to want to buy and wear your product.
If you think deeply how you have ever come to any decision you ever made in life, it always reflects what you value. We usually don't ever go against our values when making decisions. Of course there are circumstances when possibly we have but overall we are true to our values, and this definitely is true when we are spending money. We really need to find the value in it in order to buy it. Most shoppers work this way. I have been in Sales for over 20 years, and have learned a lot on perception, value and how to influence people. This is just my humble opinion.
I know that you are possibly thinking that it could be your marketing that is lacking and maybe so, but you did have traffic to your site and still from what I read in your posts, you did not make the sale. There are many factors involved in catching your customer emotionally and I feel that I have touched on the major points in this post. Sorry for such a long post, but I really hope I have helped you some.
Over all, I think you are a very creative person, and if you dig deeper into your creative mind, and connect the value with your designs you will possibly be more successful.
