It's always nice when a vendor decides to upgrade their website, something a lot of companies forget.
But on that note i would like to help you with a few mistake i think you have made, and you could benefit from changing. I do this because i like your site, and the products you sell.
One of them is something called redirects or permalinks. The idea is that your links may never change, but if they do you should at least redirect the user to the new url where the same content is placed.
Right now if one of your products is linked from the old site eg
http://www.pvc-u-like.com/store/showitem.asp?id=2448, all you will get is a blank page saying "The page cannot be found".
This creates an issue because people who have linked to your products from a lot of different sites will get a blank page when they click on the link, and then you may have just lost a potential sale.
Another issue is that you also lose page-ranking (SEO) from all those old links because they are invalid.
The good news is that you can fix this by creating redirects from the old urls to the new urls where the product is located.
Of course there will be a lot of manuel work creating all those redirects for all the products, unless you have a document which maps the old product ids to the new ones. In any case i would say it is worth it.
An easy fix to this problem could be to redirect all old urls to the mainsite so they don't get the blank page, this is of course your call.
Another thing that i find a bit annoying which were also the case on the old site, is that it is hard to figure around in the different colors / materials. It would be nice if there were pictures of all the different variants of the product. I know that this would be a
major piece of work but if there at least were the color names on the product which you had pictures for, that would be nice.
An interesting thing for you to measure according to sales is if products with pictures / color description is selling better than the ones without. This could motivate to get more pictures taken.
I have noticed that you with the new site already have tried to make it easier to choose colors by updating the picture with the corresponding color when choosen in the dropdown. This is nice but could use a bit more work.
One issue that i find annoying is that when i have selected one color, it is not possible for me to use "arrow up / down / left / right" to change the color / picture, since it only updates with mouse clicks. This should be easily fixed by making it update when the dropdown has been changed, or on arrow key use.
Something else that i would also like to see with the color chooser is an easier way to select the colors than the current dropdown. Maybe a dropdown which showed a small thumbnail of the pictures. It could also be nice with some categories in the selector like solid materials, transparent, semi transparent and so on.
Another problem i have notice is that none of your pages except the mainpage and contact have a title.
If you look at
http://pvc-u-like.com vs
http://pvc-u-like.com/proddetail.asp?prod=RA08 you will see that the first one in the addressbar / tab area have a title called "
PVC-U-LIKE : Your one stop shop for PVC Plastic Vinyl and Rubber Clothing" where the other doesn't have any and the browser usually default to showing the url.
The second one should of course in the title read "
Fashion Jacket" which is the product on the site.
This might be something you need to change a setting in your e-shop solution, or contact the developer who made it.
And last; i feel you have taken the site more towards making it a sex shop site with the sex toys category, instead of a fetish rainwear site. I remember some of the products being there before, but i just feel they just do not fit in, and you should remove them. This if of course just my opinion.
I hope you will look into this and consider my ideas and that you see this as constructive criticism and not negative.
Feel free to ask me if you feel you need more information on the subject.
