OK, I have done some poking around and learning through trial and error how HF handles their part numbers... I found this site which lists some of the current discount codes:
I have been playing around with their numbering system and it seems that the suffix, particularly the letters after the hyphen, are the ones that determine the pricing of the basic item number before the hyphen. For example, if you go to place an order from the website for the solar
panels, it comes up as $199. If you click the "order from catalog" button and enter the same part number as the website but the suffix from the catalog, you get the $179 pricing.
It works for other stuff, too - I was looking at a 5-watt fluorescent shed light
with a remote-mounted solar panel
and it was $39 on the website. It wasn't listed in the printed catalog that had the cheaper price on the solar
panels, but if I used that catalog's suffix, the price popped up as only $29.
There's also a 20% off your whole order coupon linked there, but it's only good for in-store deals, not catalog or internet. I don't have any stores near me. I suspect that this would be the best deal of any.
There is a list of HF retail stores here: http://www.harborfreight.com/cpi/ctaf/retail_stores.taf
So, to get the $179 price on the solar
panels with an online order, find part #90599 on the website (which will come up as #90599-1VGA and be listed at $199) and add it to your basket. Then, click the trash can to remove it from your basket. You'll also be presented with an option to order from the catalog. Click that button, then enter part #90599-4RPH
. Presto! Price is now $179. Don't forget to also get the free attache' bag plus $5 off your order by entering Special Gift Item #35233-0RPE or one of the others listed on the billt site I linked above.
It seems that the number in the suffix is not important, but the three letters are. If you wish to buy other items, try going through the same steps like I did with the shed light
and you might get some decent pricing. It's too bad they aren't offering free shipping any longer - probably a casualty of the incresed prices for fuel and transportation.
Hope that helps - let me know if it doesn't work out.
