So I'm doing math on the diamonds:


 * 20 @ $1.99 = 0.0995 per diamond. At this rate the following is true:
 * 60 diamonds would cost $5.97, which means that they are 5/6 of the original price, not a 20% discount. Instead it's 20% of the final cost has been removed from the original cost.
 * 250 diamonds would cost $24.875 (or $24.88 when rounded to a penny), which means that they are 4/5s of the original price, not a 25% discount. Instead it's 25% of the final cost has been removed from the original cost.
 * 550 diamonds would cost $54.725 ($54.76 rounded), which means . . . that I don't feel like doing the math, but I suspect the math is the same and that it's not a 37% discount and instead removed 37% of the final cost from the original cost.
 * 1500 diamonds would cost $149.25, which means that they are 2/3 of the original price, not a 50% discount. Instead it's half of the final cost has been removed from the original cost.

Now, on to some of these. They all say the discount is the same, so I'm curious.
 * 180 would be $17.91.
 * At $4.99 this is a rate of 2.772222... per diamond.
 * At $7.99 this is a rate of $0.043888... per diamond . . . you are definitely paying for the convenience of 14 days instead of 28 for the one above.
 * 400 would be $39.80.
 * At $9.55 (current conversion from 499 Philippine pesos) this is a rate of $0.023875 per diamond.
 * At $10.07 (current conversion for 36.99 AED) this is a rate of $0.025175 per diamond.
 * At $12 (conversion made by someone else for Czechia) this is a rate of $0.03 per diamond.
 * 850 would be $84.575.
 * At $19.99 this is a rate of $0.02351... per diamond.
 * At $21.08 (current conversion from CAD) this is a rate of $0.0248 per diamond.

Those are the ones I saw and the info I could garner without too much effort.
