I've purchased two pretty large posters - one B3 (36 × 51 cm) and one B2 (51 × 72 cm).

I've also purchased a VHS and may add some other items (books, DVDs etc.) over the next few days. It's all currently sitting in Buyee waiting to be consolidated.

I'd like to receive everything in the cheapest way possible (to Australia), so I was wondering whether it would be better to:

• Consolidate everything into one package once all items arrive? or...
• Consolidate the 2x posters into a separate package (ideally together in the same tube) so they don't make the VHS/books package unnecessarily large and expensive.

I asked Buyee directly and their answer was basically "it's usually cheapest to consolidate, but sometimes it might not be", which left me more confused than before. What would you do?
