Considering he's apparently had a fish shop for 15 years, he's got terrible grammar and spelling. You'd think he'd try to at least put it through a spell check, or something, just to ensure professionality. Must have been a great fish store.
Here are some examples;
..."IT LOOKS AFTER ITS SELF FOR YEARS" could be correct, but is still improper. It should read 'it looks after itself for years'
"WELL AS IM A SPECIALIST I WILL TELL ALL IN MY REPORT." should be 'Well, as I'm a specialist, I will tell all in my report.'
"CLENLINESS..." should be, obviously, cleanliness.
"...RUNING..." should be 'running'.
"...BUY WAY OF PHONE..." should be 'by way of phone'.
"...IMFORMATION..." (2x) hahaha, I don't even think he read over this decription.
"...BRAKING..." in that context should be 'breaking'.
That's not to mention the plethora of sentence fragments, improper punctuation, and all else that would cause an English teacher to cringe. Don't waste your money, this can't be much of a deal. If he's really that intelligent in terms of this information, he would easily be able to publish a book, and sell it for much more than $0.99 a pop.
Also, judging by his feedback (which is loaded with what appears to be stolen cell phones, car parts, and software), this seller seems like a shady character (and certainly not the owner of a fish store). Don't waste your time or your money.
