What is Max Bag and Mon storage now ?

I don't think they're going to do an item upgrade sale any time soon at all. They just upgraded the bag from 1000 to 1500 3 weeks ago. It would be a slap in the face to all those who spent 2000 coins to max it out if they put it on sale now. I would guess it won't be for another 6 months at least.

Even without a discount it's the best buy in the shop. I would never throw out pokeballs, and certainly not revives or potions. Although I have nearly 300 red balls now, I remember the days - before gyms doubled as stops - when I constantly ran out and had to buy them (100 coins for 20 balls is no bargain!)
