Depends. Heavy products in the store include cat litter, cat scratching posts/trees, aquariums, dog crates, etc. If you are a cashier, you MAY be asked to help the customer carry these to their car. If you are in the fish department, you WILL be asked to help carry aquariums to the customer's car. If you work stocking shifts, you will be responsible for clearing pallets of merchandise and loading them on to the shelves.
