I have found that it is quite useful to figure out the restock intervals of each shop so that I don't have to waste time refreshing when there won't be a restock. Here is a very very short list of the shops I restock in (don't judge, new account >.<):
1: about every 10 minutes
7: about every 15 minutes
2013-12-03 15:58:59 - Bought Scorched Veggies: 199 NP in 3437ms
2013-12-03 16:10:22 - Bought Draik Wrap: 222 NP in 2604ms
2013-12-03 16:19:30 - Bought Peanut Butter Tonu Crackers: 888 NP in 2360ms
2013-12-03 16:31:23 - Missed Purple Hamburger: Sold out.
2013-12-03 16:44:18 - Bought Strawberry Ixi Fizzy Drink: 666 NP in 2109ms
That's around 10-15 minutes
2013-12-03 19:13:46 - Bought How to Make A Pteri Plush Doll: 333 NP in 2183ms
2013-12-03 19:34:08 - Missed Disco Moehog Dancing: Sold out.
2013-12-03 19:40:12 - Missed Acara Anatomy Book: Sold out.
2013-12-03 19:56:28 - Bought Every Shoyrus Handbook: 1188 NP in 2340ms
2013-12-03 20:06:03 - Bought The Grumpy Grundo: 1233 NP in 2229ms
2013-12-03 20:16:06 - Missed The Secret Journal of Agent A: Sold out.
That's about every 10-20 minutes.
How to collect data: Use ambrosia and make sure you buy something/miss something every restock (a lot more possible on half price day). Go to your autosave and paste the first buy every restock. Now you can see intervals
If you guys could help expand this list, we could make a very useful guide for restocking! Thanks and have fun RSing
