In the holiday ops you are able to get discounts on tech tree tanks. For the Tiers 2 to 6, the discounts are greater than 50%, which means, if you buy them with discounts and afterwards sell them again, you make profit.
So I was bored and i looked up which tanks are the most expensive, and if Im not mistaken, this should make you some credits if you don't want to keep tanks of these tiers.
- Tier 2: Italian [4.100] 100%
- Tier 3: Italian [45.400] 100%
- Tier 4: B1 [185.000] 100%
- Tier 5: T1 Heavy [435.000] 80%
- Tier 6: Hellcat [950.000] 60% (Also O-I, but since Top of the Tree, it might not work)
So the combined price you'd have to pay is 467.000, and afterwards sell them for combined 809.750, which makes a total profit of 342.750 credits. Keep in mind to buy tanks without ammo and crew if you do so.
