Here are notes from reviewing a few pages:
On Front page
>> bar’s, restaurant’s, store’s
Remove apostrophes.
>> One the best things
"One of the best things"
>> About Us
The "About Us" heading is misplaced on this page and the "read more" link page. The "healthy alternative" text is not "About Us".
On Starter Kit detail pages
The large top photos are off center and outside your white content boundaries on the right edge. Nice shots btw.
>> Atomiser vs. Atomizer
Use only one spelling of the word.
>> It’s
Remove apostrophe.
>> Thats
Insert apostrophe.
>> A complete electronic cigarette comprises of
"A complete electronic cigarette is comprised of"
>> fully compatible with the
njoy Electronic Cigarette
If you are going to mention Njoy you probably have to indicate that Njoy is a trademark. The J should be lower case unless the whole name is capitalized.
One of my penstyles is a DSE801. As a consumer I might wonder if yours is also compatible with the 801 (esp. since you mention one model and not the other).
As a consumer I prefer to see model and compatibility information set apart cleanly so I don't have to search for it amongst other text.
On Cartridge detail page
The large top photo is off center and outside your white content boundary on the right edge.
>> Regualr
Typo, regular.
