I am now selling goods that require next day delivery (they're aquatic shrimps) and they therefore have a shipping cost of £6.95.

At the moment my shipping is based on weight and the shrimp themselves weigh virtually nothing.

Goods weighing over 2kg cost £6.95 to send and I could put the shrimp weight at 2kg each (this would in a sense solve my problem). However if a customer clicked on estimating shipping and purchased 10 shrimp, the weight would show 20kg!! Would this matter or do you think that is odd?

Lastly, if customers spend over £50 they get free shipping. However with shrimp it can never be free shipping as they need to be sent on their own at the shipping cost of £6.95

Hope this all makes sense but I look forward to any advice.
