Frequently Asked Questions
Why did you create the site?

Honestly, for selfish reasons. I wanted to find parts and it was a pain to watch multiple forum threads and retailers. After a short bit, I realized others could benefit from the information so it was made public. I did have to slap some lipstick on the pig, but I promise no pigs were harmed during the creation of the site.
Why are some listed items out of stock when I click on the link?

It has gone out of stock since the site last looked. While our scanning is non-stop, there are breaks in between scans for individual sites. This is to not tax either our scanner bandwidth or the retailer site being scanned. The break time in between scans depends on the amount of individual pages being scanned.
What do the numbers next to the part types mean?

I have included numbers to indicate how many are currently in stock out of how many we are scanning for each part type. So, if you see (10/512) that means we have found 10 sites/pages of that part showing stock out of the 512 sites/pages we are scanning. These numbers do not indicate the amount of stock any one company has on hand.
Why do some products appear on the Newest items page when they were already in stock?

Technically, they were out of stock (OOS). What likely happened is that the scan engine was unable to reach the page for some various network reason and it will not assume that the product is still in stock. Because of that the product will be removed until the next scan. The next scan will think it's found something that was out of stock but is now in stock. I think this is better than assuming something is still in stock if I can't find out.
What is the Last Out-of-stock Items link do?

This list is built based on items that we have seen in stock, which are now out of stock and have been for more than 5 minutes. I set this as 5 minutes to cover items that go out of stock and back in stock very quickly, likely due to network issues or company site issues. Oddly, some may not even want this page as it only serves to "poke" at those who missed a deal they really wanted. I find it helpful in conjunction with the filter to see when a set of items I want was last in stock.
What is the Popular In-stock Items link?

This shows the top 200 historical items of interest based on visitor traffic out of the site, which are in stock as of this moment. When a product is scanned as out of stock, it will not be shown on this page anymore until it comes back in stock. Basically, it's just an interesting list to gauge what others are researching or buying.
How did you choose the sites you scan?

From feedback on merchants via forums we visit regularly. Basically, if more than a couple people have vouched for them to others... we investigate the company site for inclusion to the scans. While we don't endorse any company listed, we try to make sure that someone has based on positive purchase experiences.
Why don't you have XXX part type listed as an option?

I am adding new part types as I can identify good sources to obtain the information. I have a list of ones we still wish to add to the site and will keep working to get those done.

Why aren't you scanning XXXXX site?

In some cases we may not be aware of the site. Also, some sites have really tough pages to scan as they don't use modern html conventions. Some sites only have a few items or they don't have expectations of stock for a long time currently, which would require significant work to support their site with nothing to show in the end. Visit our Facebook page and suggest a company. While you are there, go ahead and hit "Like" to share the site with others.
How does all this work?

Without going into a lot of probably boring details for most, the site uses a custom html scraping/parsing engine that I created from scratch. Engine is usually scanning between 5 and 20 retailers every moment. Results go shooting into a database. Site reads database and shows results based on what you requested (part type or advanced search).
I'd like to help! How can I help?

Right now, I would appreciate you just sharing the word about the site. You can click the share links above to use social media and help us grow. Also, if you happen to need anything that Brownells carries (which is a lot), please visit them through one of the Brownells banners or product links as we get a few pennies per sale to help pay for hosting.
How can I advertise?

Please visit the Advertising link. It's also at the top of every page.
So, is it "in stock" or "in-stock"?

Good question as we had to look up why it is seen both ways often. According to one source (which we agreed with), if the words precede the noun you are identifying then you compound the words with the hyphen. Otherwise, you do not hyphenate them. This is why you see mixed usage of the formatting in the site. I tried to follow the rule.
