I'm the same, really depends but I always check Amazon. Lately, Rock Auto has been the best price on high quality parts even with shipping. I prefer to go with higher quality to not do the job again. If I can get a better price on the same part, I go for it. Nowadays it's really all about getting the best price and with the internet, you can shop around in the comfort of your house or on mobile when on the move.
Today, the Supreme Court of The United States ruled that states can charge online sellers sales tax even if they don't have a physical presence in their state. For years, online retailers have been able to sell without charging their customers sales tax, which gave them a leg up over traditional brick and mortar stores. This is a big win for retailers that have a store front and could never avoid charging sales tax, it evens the playing field.
How states enact this on a state by state level is still to be determined. Many states today have put into legislation affiliate nexus laws, and the states that haven't will soon change to collect tax revenue. Small online retailers stand to take the most hit on this. From small website sellers to Amazon and eBay marketplace sellers, they'll soon have to charge sales tax. This will affect all kinds of sellers, including those that sell auto parts and don't currently charge sales tax.
States will be able to charge sales tax on online purchases thanks to the Supreme Court
My other 2014 chevy equinox stared to make noise and after about a week or so it good enough of a hum to be able to identify what wheel was making the noise. I looked around online for a replacement but ended up going with the AC Delco OE from rock auto because the price was less than some of the aftermarket moog and second like versions at the major retailers. Replaced and working good. If you do one of these, you need a slide hammer to get it out, even though it's bolted in.
