Shops

They will have multiple purchasable sales and tiny shops within.

Event Special Sales (where there is one) and buyable with real currency is always listed at top.

Special shovels and hammer sales when they happen. They can only be purchased with jewels.

Then the daily item sales. You can purchase items you don't have yet too! Which is great for stocking up. Purchasable with just coins.

They have squares of collectible deco items, present boxes, shovels, hammers, etc. You can purchase with jewels and coins. Don't forget to check them daily for free items, such as, white present box, 100 coins, 5 jewels, rarely a collectible deco item.

The last shop is where you can buy jewels with your real local currency. I won't be listing here as the prices vary from currency to currency.
