I just placed an order on the new site. Here's my feedback:
Personally I'm not a fan of blue, but my own tests (for unrelated products) have shown that it converts well, so probably best to keep it.
You spelled "disposable e-cigarette" wrong in the nav! You have it spelled "cig
erette."
Your confirmation email is sending a copy of the CS Cart logo - as an attachment.
In the bar where the previous orders and wish list are, you have not standardized the capitalization. You should. You have it "Previous Orders" (title case), yet "Wish list" has the second word in all lowercase.
In the bestseller images on the front page, your almond e-juice says to contact you for price. I see that the price shows when the image is clicked, but who's going to do that when it says they have to contact you? I only clicked it for the purposes of this review, since that's not my preferred flavor.
All of the top 10 say to contact you for price when moused over. It makes it look like the site's not really open, or at best, that it'll be a huge hassle to do business with you. Your regulars probably won't even bother checking any of that (instead they'll just go to what they want, like I did), but new customers will certainly notice.
The positives are that the site's easy to use and the search works.
The reddish header is cool, other than the fact that you should not capitalize words in the middle of a sentence. You have "hardware" capitalized. It shouldn't be. The same problem exists under your main captions for e-juice and hardware.
I'm seeing an odd half-a-star image next to the "HOME" button in the horizontal blue nav bar.
All in all, I mainly care about getting my e-juice. The ordering aspect worked fine, and thanks to the search, I didn't have to remember how you categorized it. So, the site works fine enough.
Since site reviews have been deemed welcome, however, you have gotten one. Hopefully you will at least fix the spelling and capitalization issues right away! I spotted them immediately.
