Main page
black heading font - b's, d's, and e's look rather strange in google crome (b's and d's are oversized, and e's look like o's with an extra line through the middle)
under Desktops & Laptops - "Bought a PC one" do you mean "PC once" or is that a brand name I've just never seen?
under Affordable Solutions for Lansing, first paragraph, last line - "our Number 1 Goals", I would capitalize "our" in keeping with the general capitalization theme of the page.
under Our Geeks Don't Come From a Retail Store, last sentence - "keep our own low while, and as always, provide great service" should be "keep our own low while, as always, providing great service" or "keep our own low while still providing great service"
Services page
under More Than Just Your Average Computer Fix - "When you want your computer, home theater, smartphone, mobile device, and other technology" personally, I would use or instead of and, but it is grammatically correct either way.
under Services For A Mobile-Digital World, second paragraph - "do not hesitate and contact us now" would be improved by saying "do not hesitate to contact us now"
under Online Backup: Free & Easy - "Backup all your important data on a computer located across the computer", I assume you mean to say "on a computer located across the internet" or something to that effect.
last sentence of same section - "we off free subscriptions with every appointment", I'm quite certain you mean to say "we offer"
under Polished. Professional. Certified. - "Professionals with intense experience", you may wish to replace "intense" with "extensive"
under Need Something Else? - "broad knowledge and experience let's us solve", should be "lets" not "let's"
About page
under Polished - "We consistently train, study, and work diligently" I would recommend changing "consistently" with "constantly"
under Different From The Big Retail Stores - "Our Experts constantly impress", this is where I would use "consistently"
under Nationally Certified - "Our Experts are constantly receiving new training and stays updated", replace "stays" with "staying"
Contact page
I can't find anything I'd change on this page.
Overall, it's a beautiful website. Don't take the long list of suggestions as criticism. I've rarely encountered websites that didn't have several of these easy to overlook issues.
