Seller with lots of completed gigs but no multiple-purchase option?

Hello,

I am dealing with a seller that has completed lots of gigs (500+) - and they all look great and have high ratings. Now, when I go to buy gigs from this seller I have no option of multiple purchases (ie: order quantity is only '1').

My understanding is that a seller with so many gigs should be at a higher "level" that would allow me to buy multiple gigs at once - so I'm confused.

How could a seller have so many completed orders with a high rating and still not have the option for multiple gig purchases? Is something dodgy happening?

Thanks.
