New LEGO Harry Potter GWP’s required spend also requires a little maths

40577 Hogwarts: Grand Staircase is available now – but if you’re hoping to grab it with the new summer sets, you’re going to need to do some maths.

Orders of £130 / $130 / €130 on

sets will qualify for 40577 Hogwarts: Grand Staircase, which is built to the same style as the rest of the current modular Hogwarts system (albeit without any obvious points of connection), through July 31. Fortunately, there’s a brand new wave of Wizarding World sets to pick up, so surely one of those should do the trick. Surely.

Well, no – unless you’re in Europe, where

just tops out at €129.99, none of the new wave of sets alone is enough to reach the threshold for 40577 Hogwarts: Grand Staircase. Instead, you’ll need to come up with some combination of sets that passes £130 / $130 / €130 in total. Here’s a brief reminder of the latest range, along with their RRPs:

– £17.99 / $19.99 / €19.99
– £44.99 / $49.99 / €49.99
– £69.99 / $79.99 / €79.99 
– £89.99 / $99.99 / €99.99
– £44.99 / $49.99 / €49.99
– £79.99 / $89.99 / €89.99
– £114.99 / $119.99 / €129.99

Looking at those prices, a few obvious combos immediately jump out. You could pick up the biggest and smallest sets of the wave, for instance, in

and , which would come in at £132.98 / $139.98. Or you could aim for and either or , which totals £134.98 / $149.98.

If you’re in the US, you could substitute

for in that combo, which would bring the total back down to $139.98. It would only reach £124.98 in the UK, though, which isn’t enough to qualify for 40577 Hogwarts: Grand Staircase.

One last option (at least for getting as close as possible to the required spend) could be to pick up

, either or , and . Either combination of three sets there would come in at £132.97 / $149.97. A better bundle in the UK, for sure.

All this is only considering the newly-released wave of

sets, of course, and there are plenty of others still available if you’re not already caught up on the Wizarding World theme. But for those of us who do only need the new stuff, placing the spend threshold for 40577 Hogwarts: Grand Staircase at £130 / $130 / €130 – a full £30 / $30 / €30 more than the required spend for last year’s 40452 Hogwarts Gryffindor Dorms – doesn’t feel especially consumer-friendly.

Still, any order that reaches the threshold for the boxed freebie will also qualify for 30435 Build Your Own Hogwarts Castle – currently free with a £40 / $40 / €40 spend on

sets – and free delivery, sweetening the deal just a little. Both 40577 Hogwarts: Grand Staircase and 30435 Build Your Own Hogwarts Castle will be available until July 31, or while stocks last.
