In addition to spending limits, there is also a limit on the number of orders that you can place within a 24-hour and 30-day period.
Level 1 users have a monthly limit of 20 orders, and level 2 and 3 users have a monthly order limit of 30 orders. For orders placed with a bank card (credit/debit/prepaid/virtual/gift/etc), there's a daily order limit of 5 orders which is applicable to all levels.
Circumventing the order limit
If you live outside of the SEPA zone or UK and you're weekly/monthly expenditure is 1,000 USD or above, know that placing your order with a SWIFT bank transfer will save you 5% on your transaction's total cost in fees, meaning that you'll save a minimum of $50! (If you live within the SEPA zone, then this applies to any bank transfer order!)
