Not a great first experience and not necessarily reflective of GoBanana but more the Seller of the product. I ordered 18 bags of Slab Layer and received notification that the Seller had a problem with their product feed affecting the product price and delivery charge. My order had to be cancelled but I could re-order with new product and delivery price. The link attached to the email showed that the cost of each bag had risen from £6 to £11 - I didn't bother checking the cost of delivery. Very disappointing. Having gone back in a couple of days later, it looks like the price has reverted to £6 per bag with a delivery cost of £15. How can I trust this Seller to honour if I ordered again? Phoebe - thanks for letting me know quickly about the issue. Unfortunately the overall experience is still poor.
