Saphire Lilycove FINALLY having a sale! What should I get multiples of?

[Stonewall]

Well, considering I finsihed the game a couple of months ago (?) and have only JUST gotten my first lilycove sale, I figure I should get everything possible becuase I may never have another sale. My question is, does each sale have random items, or does every sale have all the items that you can only get during a lilycove sale? (does that make sense?)

Also, what items should I get more than one of? I was thinking I should get at least two or three boards just in case I come across a secret base I want that has either more than one hole or has big holes in it. How many boards would be enough? And also, besides the boards, is there anything else I should get multiples of (or fill my inventory with) be it items or secret base decorations or what? Any tips or things I should be buying as many of as I can now that I have the chance? Thanks for any advice. The sale starts tomorrow I just found out (Sunday for those in the North American Pacific time zone) thanks to anyone with advice! thanks!

I personally bought two stands and slides in the sale... i just like having a base with them in, thats just my opinion tho...

I never got to the sale yet. What do you have to do to get the sale?

[Salamence-trainer221]

Once you defeat the Elite 4 you should get the sale sometime after. It's completely random when you get it though. I have about 15 hours of playtime after the Elite 4 and have yet to get the sale.:(

That's funny. The ONLY special events that ever happen on my Sapphire are those bloody sales. I've got like eight tires.

I think it's more common in emerald, I get them fairly often.

If they're that rare for you, just get stupid amounts of everything the first chance you get. It's not like money's a problem.
