Apart from deposits and withdrawals, which transaction has a higher pay-as-you-use fee than an EasyPAY fee?

The fee is R8 per R1 000 (or part thereof).
For R2 890, this is considered 3 units of R1 000 (R1-R1000, R1001-R2000, R2001-R2890).

$$\text{Pay-as-you-use charge} = 3 \times \text{R}8 = \text{R}24$$

The fee is R10 + R2,30 per R100 (or part thereof).
For R2 890, this is considered 29 units of R100 ($\lceil \frac{2890}{100} \rceil = 29$).

$$\text{EasyPAY charge} = \text{R}10 + (29 \times \text{R}2,30) = \text{R}10 + \text{R}66,70 = \text{R}76,70$$

The Pay-as-you-use account is more cost-effective for this specific withdrawal.

The difference in charges is $\boxed{\text{R}52,70}$. The Pay-as-you-use account would be more cost-effective for this withdrawal.

Thabiso might remain with his current Pay-as-you-use account because he primarily uses free transactions like point-of-sale (POS) purchases, making the overall monthly cost of his banking manageable despite higher fees for certain withdrawals.
