Midway USA has Mini-Mags on sale in their March Flyer .
They have both 36 gr and 40 gr per 500.$29.99 36 gr
40 gr $29.49.5000 40 gr for 4264.99 This may be a good price for some people,not for other`s.
That's not a bad price but with shipping I think it would be the same or more than Walmart's everyday price on them. I'm looking into getting them in bulk (5,000+) from my local gun shop. I just did that with 9 mm (1,000 rounds) and 45 (2,000 rounds) ammo this week. I'm gonna end up on a list.... LOL
