I just noticed that the Delicando newsletter rebate applies to gift cards (only the printed ones):

If these gift card codes can be combined with the newsletter rebate (which seems likely), the rebates can be stacked using another account.
This should be repeatable ad infinitum (buy gift cards with the newsletter rebate, redeem them with another account and buy new gift cards using the rebate again).
Using both the 15% newsletter rebate and the 1% rebate for paying by wire transfer:
- 1st account: buy 180€ in gift cards for 151.47€
- [wait for shipment]
- 2nd account: buy 220€ in gift cards for 185.13€ (total cost: 156.60€)
- [wait for shipment]
- 3rd account: buy 270€ in gift cards for 227,21€ (total cost: 163.81€)
- etc.
(rounding down and leaving a tiny bit of the gift card behind if necessary would be slightly more efficient, you’d be at 250€ having paid 151,47€ by the 3rd account)
If anyone wants to try this, I’d suggest you set up a couple of new accounts beforehand (i.e. register for the newsletter, check that the code “NewsletterDelicando” is applied correctly and leave something in the basket so the code stays applied).
And I’d suggest you pick something you’d want to buy with the 1st round of gift cards if the rebates can’t be stacked.
(please report back if you try this)
