What?
So, lots of people have donated in the past and have always been unsure about which items they should buy. I have created it this for personal reference but someone might find it useful?
What to avoid?
Common sense really, most people don't want series 4 chests and due to the past, there is a lot of series 5 chests around for people to buy. Tier 2 and 3 chests can be good, but right now, most people don't really care for the effects.
Prices?
Rare Tier 1 Chest
All of the tier 1 chests have roughly the same price minimums, they all yield a rare and due to the magic dust update - all rares tend to have a minimum price of around 3m.
S1 - S3 Chest Bundles
I would avoid the Series 4 and 5 bundles due to the lack of demand in the chests. Series 1 to 3 chests usually sell for around 50k minimum. You are also given 10 keys when you buy a bundle.
10 Chests = 500k
10 Keys = 6m
--
6.5m
Mysterious Chest A
These bundles yield 8 Mysterious A chests, and 8 keys. They are valued at:
8 Mysterious Chests = 1.6m
8 Keys = 4.8m
--
6.4m
Mysterious Chest B
8 Mysterious Chest B = 4m
8 Keys = 4.8m
--
8.8m
>>>
This means the best option if you are going to donate and buy some items would probably be..
For Money, Mysterious Chest B
For Rares, Rare Chests
If you're lucky then you should consider 8 Mysterious Chest A!
But remember! If you're a Diamond VIP you can buy 3 gold bars and then use this to buy 10 S1 - S3 bundles - make 10 mysterious A chests and 30 keys!
