looks like phils tire service is doing a group buy/quantity discount on their Joengbloed Wheels.
The base pricing on these is $115 each, plus free shipping.
As more people buy, the price goes down. Not a bad chance to get some fresh wheels for the season.
See below from a different forum:
Phil's Tire Service is offering a great opportunity to buy a set of the premier Spec Miata Wheels
on the market today at a fabulous discount. The AERO PTS Spec Miata 15x7 Wheel. The JRW PTS SM wheel is offered in Satin Black or Gloss Silver at +25 or +30 offset. 13.2lbs Regular price is $115 per wheel.
Group buy sale ends Jan 12th or when the 40 set level is reached, whichever comes
1-10 sets $460 + Free Shipping
11-20 sets $460 - $23 ($437) + Free Shipping
21-30 sets $460 - $34 ($426) + Free Shipping
31-40 sets $460 - $45 ($415) + Free Shipping
Credit cards will not be charged until sale ends or the 40 set level is reached. All
add on items will be charged shipping unless they are already a free shipping
Everyone will pay the highest level reached (lowest price with FREE shipping) regardless of when you sign up.
Therefore, there is no advantage to signing up at the last minute and every
advantage to signing up as soon as possible to avoid the sale ending early
because of the maximum level being reached.
