Top players always consider delivery cost. If delivery is 30% of the total basket amount, don't buy it - wait until you have other coins you wish to buy as there will very likely be offers in the future* - perhaps even free delivery with a price discount.
*You have nothing to lose even if there is no offer, as RRP and delivery cost are unlikely to increase.
The NEW Agatha Christie £2 Coin Pack is released on Monday 14th of September - please be patient, do not buy this coin pack yet and pay the expensive delivery charge for 1 coin. Wait and watch the Facebook coin groups for a good deal or a bargain on this coin.
Don't forget that wholesalers sell BU packs as low as £5 net of VAT - so look for discount codes and support trusted Facebook sellers, to get the same coin at a better price with cheaper delivery too.
