That's where QBP (parts supplier) is located, so unless Jenson has an item "IN STOCK", it'll ship from Minnesota. To check where it will ship from before you buy, you can go through the normal Checkout process but when you select your delivery method, choose that you'll pick it up In Person in Riverside and if it doesn't say same-day pick up guaranteed, then they don't really have it IN STOCK & it will ship from Minnesota. I almost always check to see if an item is really in their Riverside Warehouse before I purchase because shipping from Minnesota is painfully slow when there are usually other options that'll ship out of CA, WA or UT.
