No, RepricerExpress does not support shipping bands.
When using RepricerExpress you must use fixed shipping prices for your products. Your shipping price is saved in RepricerExpress and is used to calculate your price correctly when repricing.
Amazon to allow you to have shipping bands setup, but this causing problems with repricing. If a product is pricing up and down from one band to another this can result in your listing selling below min or above max, or simply incorrectly so you are not matching the competition.
If you have your shipping bands setup as below and you have a minimum price of £8 on a product. You could be going up and down going below £10 and back up again, this causes problems with calculating your correct price including shipping.
£0.01-£10: £5 shipping
£10.01-£20: Free Shipping
Your Min/Max price in RepricerExpress needs to include postage. So you could be priced below and above £10 with your shipping prices changing.
You could be priced at £9.99 + £5 shipping, your competitor marks their price up and your price is calculated to £10.02 + £5 shipping. Although because you are over the amount you have free shipping so are actually priced at £10.02 free shipping, so will be £5 below the competition.
Can also happen the other way around so you are priced at £10.50 free shipping, and competitors drop their price so you go down to £8 + free shipping in RepricerExpress, although you are actually priced at £8 + £5 shipping so priced £5 above competitors.
RepricerExpress does download new shipping prices, but if you are constantly changed because of going up and down between the shipping bands this will cause pricing errors as explained above.
