Guys anyone experienced in Seller fulfil prime ?..Custom made items cannot do FBA but we can do FBM .My question is FBA deliveries done by Amazon and they are so quick normally next day .But we use Royal mail 1st class meant to be next day but 10% could take 2 weeks to deliver what are the other options you can use for FBM other than Royal mail that you can trust and reasonable for prices ?. Please share your experience .thanks
